摘要
本文对形状规则的屏蔽体提出了一种新的计算方法,采用并矢格林函数法求解矢量波动方程,得到屏蔽体内的场分布,再利用小孔耦合理论得到屏蔽等效源,从而利用镜象原理求得泄漏场,最后求得屏效,并举例说明。
This paper presents a new calculation method for the shieiding body with regular form. Dyadic Green's functions are used to resolve the vector wave equation for obtaining the field distribution within the shieiding body .Then, the shielding equivalent source is obtained by using the small-operture coupling theory. In turn, the leakage field is evaluated by using the mirror-image principe . Finally the shield effectiveness can be obtained. Examples are given to explain the above method.
