Abstract

Electromagnetic scattering from three-dimensional objects are studied with finite element time domain solution of Maxwell's equations. A code based on the second order accurate solution scheme, similar to that of Lax-Wendroff, is developed and implemented. The transient solutions are obtained for two different types of incident waves, i) a single (wide- band frequency) incident pulse, and ii) a continuous wave of a single frequency. The calibration results for the code is obtained for the scattering from a perfectly conducting sphere. The results are satisfactory for the time variation of the induced surface current density distribution and the electric intensity vector field.
