The exact computational solution approach by integral representation with an application to radiation characteristics of aperture antennas

A treatise of a new computational approach was constructed in this paper. The extraction mechanism is focused on the exact evaluations of radiated field by integral representations. The approach of integral representations gives an incomplete set of equations, however; this difficulty was passed by extending boundary conditions with a matching algorithm through integral representations. The equations are solved with a scenario managing algorithm by iterative reconfigurations of radiated field. The method is explained with the radiation problem of circular aperture by illustrations. The approach is suitable for optimization purposes of antenna design.
