Abstract

Abstract

A UTD (uniform geometrical theory of diffraction for electromagnetic waves) solution for the field excited by electric and (or) magnetic dipoles on a perfectly conducting cylinder is derived by DGF (dyadic Green s function) technique at first. Then, with the fundamental principle of high-frequency electromagnetic field, the character of geometrical optics and the differential geometry theory, a UTD solution for the radiation field of dipole on a perfectly conducting smooth convex surface is obtained by directly extending the results of the canonical problem. The formulae given in this paper agree primarily with that obtained by P. H. Pathak et al. (1981) except for some factors of dyadic transfer function in lit region. Some factors derived by P. H. Pathak are corrected.
