Abstract :
Applicability of the Adaptive Cross Approximation and hierarchical matrix approach to the problems of computational electromagnetics is examined both theoretically and numerically. Reduction of the required storage and computational speed-up during each step of a numerical solution are analyzed. Numerical examples are produced using a Northrop Grumman´s proprietary code SWITCH, which is based on the hybrid FEM-BIE method.
