| Outline of Final Research Achievements |
We developed an analytical method for solving problems of the electromagnetic scattering and radiation from rectangular objects, which brought highly accurate results compared to the conventional method, and established a numerical technique for calculating the double infinite integrals and double infinite series associated with the problems with the desired accuracy. The exact solutions were obtained for various rectangular objects such as a rectangular aperture in the screen and a flanged waveguide, and we evaluated the convergence of the solution to some problems. We also calculated the various physical quantities by using the derived exact solution and new knowledge of the EM diffraction phenomena was obtained. In addition, we rigorously formulated a coupling problem for multiple apertures that served as the basis for analyzing complex rectangular objects.
