Phased Array Antennas

Phased Array Antennas: Floquet Analysis, Synthesis, BFNs and Active Systems by A. K. Bhattacharyya presents analysis and design of phased array antennas and systems. The 514-page book includes recent analytical developments in the phased array area published in journals and conference proceedings.

Efforts have been made to develop the concepts in a logical manner starting from fundamental principles. Detailed derivations of theorems and concepts are provided to make the book as self-contained as possible. Several design examples and design guidelines are included. It should be useful for antenna engineers and researchers, especially those involved in the detailed design of phased arrays. it can be used either as a text in an advanced graduate-level course or as a reference book for array professionals. The reader is assumed to have a basic knowledge of engineering mathematics and antenna engineering at a graduate level.

Schaffner Power Quality Brochure

Schaffner EMC has published a new brochure on its power quality capabilities and how these new solutions complement its EMC/EMI components business.

With the acquisition of Jacke Transformer GmbH, Schaffner has combined its leading expertise in EMC/EMI filtering offerings with Jacke’s power quality solutions to become the only company to offer that unique combination of products and services. Schaffner’s new brochure details its extensive product offerings in both power quality and ECM/EMI components. It also provides background information on the power quality industry, including why power quality is important and what some of the key issues are in the industry.

The 12-page brochure outlines factors, such as its know-how, global presence, short lead times, optimized processes and competitive costs that make up its methodology. The brochure also touches on the importance of the company’s worldwide reach and ability to customize standard solutions to meet various application-specific needs, regardless of geographical location.

To receive a copy of the catalog, contact Amelia Carrasquillo, Schaffner EMC, Inc., 52 Mayfield Avenue, Edison, NJ 08837, phone: (732) 225-9533 ext.253; fax: (732) 225-4789, email: usasales@schaffner.com.

Computer Aided Design of Wire Structures

Computer Aided Design of Wire Structures, accompanied by the related TWiNS (Thin Wire Numerical Solver) software package is an extension of the book by D. Poljak entitled Electromagnetic Modelling of Wire Antenna Structures, which is dedicated to the analysis of thin wires in frequency and time domains via an integral equation approach.

This book extends the issue of the aforementioned book, and deals with an analysis of thin wire arrays in the frequency and time domain via the TWiNS code. Using this code, it is possible to calculate the corresponding current distribution, near and far field, radiation pattern and input impedance.

The book is divided into two parts. The first part is concerned with the theoretical background and the frequency and time domain numerical modelling procedures for thin wire arrays on which the TWiNS code has been based. Frequency and time domain GB-IBEM procedures implemented in the TWiNS code are presented in detail. Many illustrative computational examples pertaining not only to academic, but also to some real world problems, are also enclosed.

The second part of the book is devoted to the description of the TWiNS code and contains the complete user manual together with some worked examples related to the frequency and time domain examples of wire arrays.
