Synthesis Lectures on Engineering, Science, and Technology

Wireless Communication Using Deep Learning Techniques for Neuromorphic VLSI Computing

Springer Series in Optical Sciences

This book presents a new view of symbiotic technology transfer between different fields in the optical sciences. For example, adaptive optics were initially developed for military research programs seeking to correct the effects of atmospheric fluctuations on telescopes. The technology was subsequently transferred to optical microscopes, and then finally used in ophthalmic imaging devices to image photoreceptors in the living human retina. This book examines various recent and historical technology transfers among the optical sciences, and attempts to answer the following questions: What are the mathematical and the physical foundations of these technology advances? What events and influences (military requirements, new journals, new funding sources, the internet, etc.) made the technologies and their transfer possible? What was the impact of technology transfer on the development of optical science? What role did the human eye and visual system play in technology development? This book examines how innovations propagate from one field to another, illustrating the benefits of cross-disciplinary collaboration.&nbsp; &nbsp; This book is about curiosity, skepticism, innovation, and creativity in science and technology, and explores practices that advance innovation and those that inhibit innovation. Analyses of some selected, pertinent case studies highlight the roles of unique individuals who were able to make the journey from initial concept to widespread clinical acceptance of their instruments. What are the common factors of their education, experiences, and approaches that resulted in their inventions and innovations?This book is intended to inspire and encourage those who dream of advancing the diagnostics and the treatment of diseases through new medical devices. It also addresses budding startup dreamers, venture capitalists, research directors, and funding agency administrators by providing new insights into practices that promote and inhibit innovation. This book should be of interest to scientists and researchers in many fields of optics, as well as technical policy makers at funding institutions.

Optical Technology Transfer and Innovation in Ophthalmic Imaging

NanoScience and Technology

The book represents quantum rings as special class of modern high-tech materials structures at the nanoscale. It deals, in particular, with their formation by molecular beam epitaxy and droplet epitaxy of semiconductors, their topology-driven electronic, optical and magnetic properties. Highly complex theoretical models are developed to adequately explain the specific features of quantum rings. The results presented in the &nbsp;book serve to develop low-cost high-performance electronic, spintronic, magnetic, optoelectronic and information processing devices based on various doubly-connected structures.The third edition contains new chapters and significantly updated and extended chapters from the second edition. It provides an ample presentation of the recent advancements in the physics of quantum rings related to spin dynamics and the spin-orbit interaction (spin interference in Rashba rings, tunable exciton topology on type II InAs/GaAsSb quantum nanostructures), the electron-phonon interaction in ring-like structures, quantum-interference manifestations in novel materials (e.g., graphene cylinders, cyclocarbons, MoS2), effects of electric field and THz radiation on optical properties of quantum rings and quantum-ring molecules. Special emphasis is made on fascinating novel effects emerging due to double-connectedness in various physical systems, ranging from the occurrence of the continuous geometric phase provoking formation of non-integer mode numbers in Möbius microring light cavities—through the inverse Faraday effect on the generation of current states in an array of superconductor nanorings—to the emergence of lightning-like magnetic flux bursts &nbsp;into a macroscopic superconductor ring.The new edition gives insight into the properties of various novel architectures, including coupled semiconductor quantum ring-quantum dot chains and concentric quantum rings, In(AsSbP) graded-composition quantum rings, topologic states of light in self-assembled and direct-printed ring-like cavities, optical and plasmon modes in Möbius-band-shaped resonators, the ferromagnetic resonance in various magnetic elements ranging from arrays of magnetic nanorings to individual 3D nanovolcanoes. It includes novel theoretical solutions to long-standing problems in the physics of quantum rings: interpretation of the observed magnetoresistance oscillations by a transmission model for superconductor quantum rings and adaptation of the Bardeen-Cooper-Schrieffer theory of superconductivity for metallic quantum rings with due account for the effects of double-connectedness on the electron properties.

Physics of Quantum Rings

This book describes a new concept in analyzing RF/Microwave circuits, which includes RF/Microwave antennas. The analysis is based on nonlinear dynamics and chaos models and shows comprehensive benefits and results. All conceptual RF microwave circuits and antennas are innovative and can be broadly implemented in engineering applications. The dynamics of RF microwave circuits and antennas provides several ways to use them in a variety of applications covering wide areas. The presentation fills the gap of analytical methods for microwave RF antennas and circuit's analysis, concrete examples, and geometric examples. The microwave RF antennas and circuits analysis is developed systematically, starting with basic microwave RF circuits and antennas differential equations and their bifurcations, followed by fixed points analysis, limit cycles, Basin of Attraction (BOA) and Stability, Stability switching. Microwave RF circuits and antennas can be characterized as chaos, iterated maps, period doubling and attractors. Additionally the book discuss RFID Antennas systems design and analysis, RF amplifiers basic and advance topics &amp; design methods, BJT transistor Ebers-Moll model and MOSFET model, Transmission lines and matching networks, Antennas system and Oscillation systems, fundamental and main parameters. This book is aimed at electrical and electronic engineers, RF and microwave engineers, students and researchers in physics as well. It is aimed for research institutes in the area of high power Laser and Target chamber interaction which need to design and use Moebius loop antennas for detecting the created EMP. It is also aimed for research institutes in the areas RF/Microwave, Magnetic Resonance Imaging (MRI), Electron paramagnetic resonance (EPR), Nuclear magnetic resonance (NMR) or electron spin resonance (ESR) spectroscopy and Electromagnetism and gives good comprehensive in RF and Microwave systems.
This second edition includes a new chapters about, Moebius loop magnetic antennas and Magnetic Resonance Imaging (MRI) RF coils systems, which both are analyzed and simulate for stability and stability switching. This second edition includes a new appendix about, Transmission lines and matching networks &amp; Antennas systems and Oscillation systems, fundamental and main parameters.
Unique features of the book are its emphasis on practical and innovative microwave RF engineering applications. These include microwave RF circuits and antennas in a variety topological structures, RFID ICs and antennas, microstrips, circulators, cylindrical RF network antennas, Tunnel Diode (TD), bipolar transistors, field effect transistors (FETs), IMPATT amplifiers, Small Signal (SS) amplifiers, Bias-T circuits, PIN diode circuits, power amplifiers, oscillators, resonators, filters, N-turn antennas, dual spiral coils antennas, Helix antennas, linear dipole and slot array, Moebius loop magnetic antennas, Magnetic Resonance Imaging (MRI) RF coils systems, and Hybrid trans linear circuit.

Synthesis Lectures on Computational Electromagnetics

This book presents the perfectly matched layer (PML) absorbing boundary condition (ABC) used to simulate the surrounding free space when solving the Maxwell equations with such finite methods as the finite difference time domain (FDTD) method or the finite element method. The frequency domain and the time domain equations are derived for the different forms of PML media, namely the split PML, the CPML, the NPML, and the uniaxial PML, in the cases of PMLs matched to isotropic, anisotropic, and dispersive media. The implementation of the PML ABC in the FDTD method is described with details. Propagation and reflection of waves in the discretized FDTD space are derived and discussed, with a special emphasize on the problem of evanescent waves. The optimization of the PML ABC is described for two typical applications of the FDTD method, firstly wave-structure interaction problems, secondly waveguide problems. A review of the literature on the application of the PML ABC to other numerical techniques of electromagnetics and to other partial differential equations of physics is provided.Finally, the design of PMLs suited to actual applications is revisited in the context of computers of the 2020’s that are, by far, more powerful than the computers of the 1990’s when the PML ABC was introduced. A simple and general-purpose method is described to design the PML in this current context.
