【摘要】 本文对电磁功率通过狭缝进入内部置有导线的矩形导电腔的耦合问题作了初步研究。用等效定理将问题分作两部份。按有关边界条件得出关于狭缝上等效磁流和导线上电流的联立方程组,用矩量法将其转化为矩阵方程组,利用狭缝和细线近似简化了计算。从典型的数值计算结果中可以看到,在某些入射波频率下,存在着关于磁流、电流和腔内场的谐振现象。更多还原

【Abstract】 The coupling of electromagnetic power into a rectangular conducting cavity Containing a Conducting wire through a slot is investigated. The equivalence theorem is applied to divide the problem into two parts. A set of functional equations is obtained, and then reduced to matrix form via the method of moments. The general formulas are simplified with narrow-slot/thin-wire approximation. Numerical results indicate that resonance exists at some frequencies of incident electromagnetic wave.更多还原
