Abstract

An iterative solver is used to compute the electromagnetic field scattered by perfectly conducting three-dimensional (3-D) objects of arbitrary shape. The unique solution of the dual-surface integral equation is approached by successive forward/backward calculations of the current. Convergence is very fast, giving accurate results in about a dozen iterations for convex objects. The method handles successfully single and multiple objects, convex objects, and cavities. Calculations can be carried out on a desktop computer for relatively large objects, with dimensions of ten wavelengths and more
