Abstract :
A two-dimensional vector integral equation for the tangential electric field distribution in a cavity-backed aperture is presented. The solution of the integral equation for a rectangular cavity by the method of moments is discussed. The expansion and testing functions are pulses in the direction of the electric field and triangles transverse to the direction of the electric field. Finally, the convergence of the solution is considered.
