| Abstract(in English) | Physical Theory of Diffraction with Transition Currents (PTD-TC) is developed to predict the electromagnetic fields diffracted by obstacles with or without edges and its usefulness is verified by applying it to perfectly conducting rectangular and ogive cylinders. Edge and transition currents are borrowed from the solution of canonical problems of wedge and circular cylinder. Transition current of curved surface is obtained by using Fock type integral representation. For obstacle with edge, the current near the edge is expressed by eigen function expansion. The current of other part is represented by Fresnel Integral, which has slightly different form from that derived Kouyoumjian and Pathak. Numerical results of far scattered patterns are obtained and compared with those obtained by MoM. It is found that the present method gives very precise results. |
