The Book deals with the theory and application of a novel Scaled Boundary Finite Element Method in Computational Electromagnetics. The novel method was initially developed in the year 1997, for solving problems in the field of Elastodynamics. It was initially developed in Swiss Federal Institute of Technology, Lausanne, by Prof. John. P. Wolf and Chongmin Song.In this book, the theory behind the reformulation of the novel method suitable for solving Maxwell's equations is dealt with in detail. As a consequence, a semi-analytical scaled boundary Finite Element procedure is developed to deal...

The far field pattern properties that are of most frequent concern to the array designer are the array sidelobe level, array gain and beamwidth. All these properties depend on the amplitude and phase excitation to the array of elements. The Adaptive antennas have the ability; to automatically respond to an unknown interference environment by steering the main beam in the desired direction, by steering the nulls and reducing sidelobe level in the direction of interference. They consists of an array of antenna elements and an adaptive receiver- processor which adjusts its element and an...
