Abstract

A time-domain version of the uniform asymptotic theory of diffraction, henceforth named TD-UAT, is introduced here and it is used to obtain the fields scattered by a perfectly electrically conducting wedge illuminated by an arbitrarily oriented electric dipole with a rapid spatial variation near the edge. An impulse response of the wedge is determined as well as the response to a pulsed source which generates a finite energy pulse. The results of TD-UAT are compared with those obtained from an implementation of TD-UTD and its applicability is demonstrated by comparing its impulse response with an exact result.
