摘要
利用广义阻抗边界条件来模拟有限导电平面对电磁场的影响。在此边界条件下，推导出有限导电平面上垂直和水平电偶极子电磁场的解析表达式；赫芝位函数中的索末菲型积分被表达成零阶汉克尔函数与绝对收敛的球汉克尔函数级数之和的形式。利用这些解析公式可方便、准确地计算和分析任意取向电偶极子电磁场的分布。
Generalized impedance boundary conditions are employed to simulate the effect of finitely conducting plane on the electromagnetic fields. Analytical expressions for electromagnetic fields of a vertical or horizontal electric dipole over the finitely conducting plane are derived subject to the boundary conditions; Sommerfeld type integral contained in Hertz potential is expressed as the sum of two parts: zeroth order Hankel function and an absolutely convergent series of spherical Hankel function. It is more convenient and accurate to use the obtained results to calculate and an analyze the electromagnetic fields of an arbitrarily oriented dipole.
