Abstract :
In this paper, a technique is proposed to numerically remove the singularities through re-arrangement of discrete unknowns, so that MOM yields correct results for all frequencies. This technique is presented using rectangular cavity backed slot (CBS) antennas as examples, and validated by experimental data.
