THE SINGULARITY EXPANSION METHOD IN ELECTROMAGNETICS: A SUMMARY SURVEY AND OPEN QUESTIONS PDF Author: Carl E. Baum
Publisher: Lulu.com
ISBN: 1105424049
Category : Technology & Engineering
Languages : en
Pages : 116

Book Description
The Singularity Expansion Method (SEM) is probably the most celebrated feather in Carl Baum's cap, among his many other accomplishments such as Nuclear Electromagnetic Pulse (NEMP) simulators, sensors, EM topology etc. SEM was born out of a simple realization that the natural frequencies of both simple (ex: a piece of conducting wire) and complex objects (ex: Boeing 747) are points in the complex frequency or the s-plane. Although expansions based on natural frequencies in mathematical physics preceded Carl's SEM formulation, he must be credited with its vast applicability in the field of NEMP during the cold war era. Coupling coefficients are described as the "transfer function" between the incident waves and the natural modes. The determination of the coupling coefficients was an important step on the path to synthesizing the responses.

Chipless RFID

Chipless RFID PDF Author: Reza Rezaiesarlak
Publisher: Springer
ISBN: 3319101692
Category : Technology & Engineering
Languages : en
Pages : 166

Book Description
This book examines the design of chipless RFID systems. The authors begin with the philosophy of RFID and its effect on commercial applications. Then, they discuss the chipless RFID systems and the application of chipless RFID systems, the advantages it provides compared to conventional barcode ID and chipped RFID tags. The text then covers chipless RFID components in block diagram representation and introduce FCC requirements which should be considered in the design procedure of each component. The third chapter is dedicated to the complex natural resonance-based design of chipless RFID tags. The next chapter concerns about the detection techniques introduced for the identification of chipless RFID tags. The fifth chapter is dedicated to the localization and anti-collision techniques in chipless RFID systems. Final chapter is chipless RFID tags as sensors. It provides some applications where the tag can be used as both ID and sensor. The tag specifications and detection issues are addressed in this section.

Modeling and Analysis of Transient Processes in Open Resonant Structures

Modeling and Analysis of Transient Processes in Open Resonant Structures PDF Author: Yuriy K. Sirenko
Publisher: Springer
ISBN: 0387325778
Category : Science
Languages : en
Pages : 367

Book Description
This book describes a systematic approach to scattering of transient fields which can be introduced in undergraduate or graduate courses. The initial boundary value problems considered describe the transient electromagnetic fields formed by open periodic, compact, and waveguide resonators. The methods developed and the mathematical and physical results obtained provide a basis on which a modern theory for the scattering of resonant non-harmonic waves can be developed.

The Method of Moments in Electromagnetics

The Method of Moments in Electromagnetics PDF Author: Walton C. Gibson
Publisher: CRC Press
ISBN: 1000412482
Category : Mathematics
Languages : en
Pages : 510

Book Description
The Method of Moments in Electromagnetics, Third Edition details the numerical solution of electromagnetic integral equations via the Method of Moments (MoM). Previous editions focused on the solution of radiation and scattering problems involving conducting, dielectric, and composite objects. This new edition adds a significant amount of material on new, state-of-the art compressive techniques. Included are new chapters on the Adaptive Cross Approximation (ACA) and Multi-Level Adaptive Cross Approximation (MLACA), advanced algorithms that permit a direct solution of the MoM linear system via LU decomposition in compressed form. Significant attention is paid to parallel software implementation of these methods on traditional central processing units (CPUs) as well as new, high performance graphics processing units (GPUs). Existing material on the Fast Multipole Method (FMM) and Multi-Level Fast Multipole Algorithm (MLFMA) is also updated, blending in elements of the ACA algorithm to further reduce their memory demands. The Method of Moments in Electromagnetics is intended for students, researchers, and industry experts working in the area of computational electromagnetics (CEM) and the MoM. Providing a bridge between theory and software implementation, the book incorporates significant background material, while presenting practical, nuts-and-bolts implementation details. It first derives a generalized set of surface integral equations used to treat electromagnetic radiation and scattering problems, for objects comprising conducting and dielectric regions. Subsequent chapters apply these integral equations for progressively more difficult problems such as thin wires, bodies of revolution, and two- and three-dimensional bodies. Radiation and scattering problems of many different types are considered, with numerical results compared against analytical theory as well as measurements.
