Abstract :
Novel time domain integral equations for analyzing scattering from perfect electrically conducting objects are presented. They are free from DC and resonant instabilities plaguing standard electric field integral equation. The new equations are obtained using operator manipulations originating from the Calderon identities. Theoretical motivations leading to the construction of the new equations are explored and numerical results confirming their theoretically predicted behavior are presented.
