Abstract :
Explicit Preconditioned Biconjugate gradient methods, based on approximate inverse are used for the evaluation of the field distributions inside an electromagnetic cavity resonator. Numerical results indicating the effectiveness of the method are presented and visualization results were found in qualitative agreement with theoretical results.
