无限长导电圆柱上磁振子辐射场的GTD近似

无限长导电圆柱上磁振子辐射场的GTD近似 GTD APPROXIMATE SOLUTION FOR THE RADIATION FIELD OF MAGNETIC DIPOLE ON CONDUCTING CIRCULAR CYLINDER 李永俊 first-author 黄锡文 王勇 对无限长导电圆柱上磁振子的辐射场,本文先给出经典解,经Waterson变换化为路积分,然后求得绕射的几何理论（G.T.D.）的近似式,从而给出了一个典型问题的解。 In this paper the classical solutions of the radiation field of magnetic dipole on a infinitely long perfectly conducting circular cylinder are given at first. After Waterson transformation, the solutions are transformed into the contour integral. At last, the G. T. D. approximate solutions are given. So G. T. D. can be extended to deal with the radiation problem. 电磁波的散射、绕射 电磁波的辐射 绕射的几何理论 国家教委专项基金 1987-04-01 2021-04-01 4
