Book Synopsis Multiferroic Antennas for Use in Biomedical Applications by : Emily Burnside
Download or read book Multiferroic Antennas for Use in Biomedical Applications written by Emily Burnside and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there is a need for low frequency (30-300 kHz) communication through lossy media like seawater and the human body, these dielectric cluttered environments present challenges to conventional communication devices in the form of signal attenuation. This is due to the interaction of the electric field component of electromagnetic radiation with the conductive portions of the surrounding media. Magnetoelectric antennas provide a solution to this problem in that they primarily output magnetic energy in the near field. Furthermore, by using strain-driven magnetoelectric antennas, antenna miniaturization is realizable by operating at acoustic resonance rather than electromagnetic resonance. While there have been successful experimental demonstrations of low frequency magnetoelectric antennas, the community lacks a systematic approach for antenna design and characterization. This first half of this work presents a decoupled system of models including a method for predicting magnetic moments of bulk samples using Landau-Lifshitz-Gilbert micromagnetic simulations, enabling radiation predictions via an analytical dipole model, resulting in a paradigm shift from dipole radiation validations to dipole radiation predictions. This work includes a methodical testing approach to assess the antenna's performance in terms of signal strength, quality factor, and radiation patterns, determining the antenna to be comparable to state-of-the-art pacemaker antennas. The second half of this work discusses the design and characterization of a Galfenol antenna which resonates at two distinct frequencies. This second antenna, called a dual band magnetoelectric antenna, allows for communication via frequency shift keying (FSK) and is the first magnetoelectric to accomplish FSK at two resonance frequencies. This work demonstrates that the data bandwidth can be increased by an order of magnitude and discusses potential for future improvement in data bandwidth. This dissertation also features a discussion on parasitic effects and mitigation techniques as well as material parametric studies for improved antenna performance. This work presents a comprehensive procedural guide for the design, fabrication, and characterization of low frequency magnetoelectric antennas, effectively bridging a gap in the existing literature.

Book Synopsis Understanding of Electrodynamics,Radio Wave Propagation and Antennas by : Eugene I. Nefyodov
Download or read book Understanding of Electrodynamics,Radio Wave Propagation and Antennas written by Eugene I. Nefyodov and published by Scientific Research Publishing, Inc. USA. This book was released on 2013-04-18 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the offered book the fundamentals of electromagnetic fields and waves are discussed based on the great Maxwell equations. The book is conceived as a textbook for serious technical and classical universities in the considered themes. Nevertheless, it can be used, of course, as the reference book for wide group of engineers, researches and practical experts. Material of this book is divided into four main parts connected between them. The first part (Fundamental of Electrodynamics) is devoted to explanation of Maxwell equations and methods of its solutions. Besides classical interpretation the generalized equations are discussed, which take into consideration the scalar magnetic fields. New approaches allow description of so-called longitudinal electromagnetic waves, which have the absolutely non-standard propagation properties, and permit to explain various electrodynamics paradoxes, which cannot be explained in another way. The main characteristics of wave processes in the free space and in transmission lines (feeders) are described. The second part (Radio Wave Propagation) investigates the obvious patterns of diffraction and interference phenomena at radio wave propagation for the obstacle presence in the propagation track, which is typical for all practical situations. Radio wave propagation of various frequency ranges is fulfilled separately taking into consideration the specific features of reflections from the atmosphere parts, attenuation in different media, types of propagating waves, multipath effects, diffraction and non-standard conditions of obstacle overcoming including non-usual ways of atmosphere ducts. The third part is devoted to description of various types and antennas, beginning from simplest (vibrators) and ending by complicate adaptive antenna arrays. Description is fulfilled on the reviewing level with many obvious figures, not to rely on strict mathematical methods, but rather on the concept level. Fourth part includes description of UHF devices, which are the elements’ base of UHF devices including surface and bulk integrated UHF circuits. These results have in many aspects the pioneer character and they are not widely known to experts. Distinctive feature of the offered book is sufficiently simplifies description of the very complicated electrodynamics problems available for the modern students and for young engineers. Of course, it is impossible to deal without mathematics in theses areas but required mathematics can be replaced by the many patterns, which give the chance to understand problems and to determine the complex questions.

Book Synopsis Meta-heuristic Optimization of Antennas for Biomedical Applications by : Aaron Zachary Hood
Download or read book Meta-heuristic Optimization of Antennas for Biomedical Applications written by Aaron Zachary Hood and published by . This book was released on 2013 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the proper conditions, antennas applied in medicine can offer improved quality of life to patients. However the human body proves hostile to typical, analytical antenna design techniques as it is composed entirely of frequency- and temperature-dependent lossy media. By combining optimization techniques with numerical methods, many of these challenges may be overcome. Particle swarm optimization (PSO) models the solution process after the natural movement of groups such as swarms of bees as they search for food sources. This meta-heuristic procedure has proven adept at overcoming many challenging problems in the electromagnetics literature. Therefore, this dissertation explores PSO and some of its variants in the solution of two biomedical antenna problems. Recent advances in biosensor technology have led to miniaturized devices that are suitable for in vivo operation. While these sensors hold great promise for medical treatment, they demand a wireless installation for maximum patient benefit, which in turn demands quite specific antenna requirements. The antennas must be composed of biocompatible materials, and must be very small (no more than a few square centimeters) to minimize invasiveness. Here PSO is applied to design a 22.5 mm x 22.5 mm x 2.5 mm implantable serpentine planar inverted-F antenna for dual-band MedRadio and ISM operation. Measurements reveal the accuracy of the models. Hyperthermia is the process of elevating a patient’s temperature for therapeutic gain. Since the ancient Egyptians, physicians have employed hyperthermia in the destruction of cancerous tumors. Modern implementations typically apply electromagnetic radiation at radio and microwave frequencies to induce local or regional heating. In this dissertation PSO is used to evaluate candidate antennas for inclusion in an array of antennas with the aim of local adjuvant hyperthermia for breast cancer treatment. The near-field of the array is then optimized to induce a uniform specific absorption rate throughout the breast.
