摘要:
研究了垂直电偶极子在覆盖有等离子体的良导体上产生的电磁场.总电磁场包括了直射波、理想反射波、侧面波和缺陷表面波.因为等离子体的折射系数是随频率变化的复杂函数,所以用于计算缺陷表面波的极点函数的解也是频率的函数.研究了频率对极点方程及其解的影响,并分别计算了直射波、理想反射波和侧面波之和、总场强、以及缺陷表面波的值.金属导体的表面在很宽的频率范围内可以等效为等离子体,本文的研究结果可以用来分析集成微带线电路或者微带天线表面的电磁场分布规律.
Abstract:
The electromagnetic fields in air from a vertical electric dipole over a perfect conductor covered with a plasma layer are studied.The total field includes the direct wave,the ideal reflected wave,the lateral-wave,and the trapped surface wave.The refractive index of plasma is a complex function of frequency,so the solutions of the pole equation which are used for the computation of the trapped surface wave are also a function of frequency.The influences of the frequency to the pole equation and the solutions are studied.
