Abstract

An algorithm has been developed for solving Maxwell´s equations for the electromagnetic field. It solves the equations in the time domain with central, finite differences. The time advancement is performed implicitly, using an alternating direction implicit procedure. The space discretization is performed with finite volumes, using curvilinear coordinates with electromagnetic components along those directions. Sample calculations of scattering from a metal square and a metal circle are presented to demonstrate the capabilities of the new algorithm.<>
