Soft Computing in Electromagnetics
Methods and Applications

Soft computing techniques are emerging as an important tool in solving design, performance and optimisation problems in electromagnetics. Soft Computing in Electromagnetics offers detailed discussion on the application of soft computing concepts in the field of metamaterial antennas, radar absorbers, transmission line characterisation and optimised radar absorbing material (RAM) and introduces implementation of soft computing tools in a relatively new area of metamaterials. The soft computing methods are used to optimise fault detection, electromagnetic propagation and path loss detection. The development of two CAD packages for design of metamaterial split ring resonators (SRR) and path-loss prediction is discussed. The concepts are explained with the help of algorithms and the corresponding software codes. Numerical examples and MATLAB codes are provided throughout the text to facilitate understanding.

Rakesh Mohan Jha is currently Chief Scientist and Head at the Centre for Electromagnetics at the CSIR-National Aerospace Laboratories, Bangalore. He obtained his PhD in Engineering from the Department of Aerospace Engineering at the Indian Institute of Science, Bangalore, in 1989 in the area of computational electromagnetics for aerospace applications. Dr Jha was a SERC (UK) Visiting Post-Doctoral Research Fellow for one year at the University of Oxford's Department of Engineering Science in 1991. He worked as an Alexander von Humboldt (AvH) Fellow at the Institute for High Frequency Techniques and Electronics of the University of Karlsruhe, Germany, from 1992 to 1993, and more recently in 2007 on AvH Reinvitation. He was awarded the Sir C. V. Raman Award for Aerospace Engineering for the year 1999. He was elected a Fellow of INAE (FNAE) in 2010 for his contributions to the EM applications to aerospace engineering. He has published a number of research papers in international journals.
