Kim, Se-Yun 2024-01-20T15:03:00Z 2024-01-20T15:03:00Z 2021-09-05 2012-04 0018-926X https://pubs.kist.re.kr/handle/201004/129364 The H-polarized diffraction coefficients of a composite wedge composed of a perfect conductor and a lossy dielectric are constructed using the hidden rays of diffraction (HRD) method. The usual principle of geometrical optics is employed to trace not only ordinary rays in the physical region but also hidden rays in the complementary region. In particular, the modified propagation constants are adopted to represent the non-uniform plane wave transmission through the lossy dielectric. The HRD diffraction coefficients are expressed by the sum of the cotangent functions, of which the angular period is adjusted to satisfy the edge condition. Some HRD diffraction coefficients are plotted here.
