摘　　要：分析了任意柱形体加载的导体劈的电磁场边值问题。对于某些特定形式的加载导体劈问题 ,导出了严格的解析解 ,从而为进一步发展几何光学绕射理论提供了一类新型的典型问题的解析解。对于一般形式的柱形体加载导体劈问题 ,则提出了基于‘全域数值边界条件’的有限元解法 ,为丰富几何光学绕射理论 。The EM boundary-value problems of conductor wedge loaded by arbitrary cylinders are treated. The analytical solutions for some loaded wedges of particular structure, as a novel type of canonical problems of GTD, are presented. And the numerical solutions of the general form loaded wedges are presented to enrich the diffraction theory, specially the theory on numerical diffraction coefficient, by offering the new numerical algorithms.
