The general programs including convex surface diffraction and edge diffr-action calculated from EEC method are programed. The resulting primary patterns of slot and electric dipole on the semiinfinite cone agree very well with exact solutions, The patterns of single slot and two slots on a finite cone are computed, The numerical results are in good agreement with measured results. The results derived are valuable to engineering. 导电圆锥 凸面绕射 边缘绕射 等效边缘电流法 一致性几何绕射理论 corducting cone convex surface diffraction edge diffraction EEC method UTD. 1988-01-01 2021-04-01 1
