本文给出了在电尺寸很大的理想导体光滑凸表面上,无限小磁矩或电矩在空间产生的电磁场的近似渐近解,利用该解可以准确有效地计算凸表面上天线间的互耦。此解中,表面塌沿Keller的表面射线路经传播,且在阴影边界过渡区域,包括对于源的邻城,它们仍然一致适用。除此之外,在给出的解中,通过一个系数T/K给出了关于表面场的表面射线绕曲的影响,其中,T表示表面射线的绕曲,K表示射线方向上的表面曲率。该解是由简单的典型问题的近似解导出的。给出了圆柱面和圆锥面上裂缝间互耦的数字结果,它与实验结果相吻合。
In this paper, an approximate asymptotic solution of the electromagnetic field generated by an infinitely small magnetic moment or moment in space is given on the smooth convex surface of an ideal conductor with large electrical dimension. By using this solution, the interaction between the antennas on the convex surface can be calculated accurately and effectively Coupling. In this solution, the surface lasers propagate along Keller’s surface juxtaposition, and they remain uniformly applicable in the transitional areas of the shadow boundary, including the neighboring neighbors of the source. In addition, in the solution given, the influence of surface rays on the curvature of the surface field is given by a factor of T / K, where T denotes the curvature of the surface ray and K denotes the curvature of the surface in the ray direction . The solution is derived from the approximate solution to a simple typical problem. The numerical results of the mutual coupling between the cracks on the cylindrical surface and the conical surface are given, which are consistent with the experimental results.
