Application of adaptive basis functions for a diagonal moment matrix solution of arbitrarily shaped three-dimensional conducting body problems

We present the application of specially constructed adaptive basis functions that generate a diagonal matrix in the method of moments solution procedure for the calculation of scattered electromagnetic fields from arbitrarily shaped conducting bodies excited by a plane electromagnetic wave. The arbitrary body is modeled using planar triangular patches. The crucial step in the solution procedure is the construction of the adaptive basis functions to generate the diagonal matrix. This task is accomplished with the help of well-known RWG basis functions. The solution thus obtained is very efficient, accurate, and applicable to truly arbitrary bodies. Several numerical examples are presented to validate the new method.
