摘要
根据孔两边场的连续条件建立积分方程,然后用算子展开方法求得了用孔面上场与标准正交基的内积表示的矩形腔内的场.采用快速逆Fourler变换求得了开孔矩形腔体对典型电磁脉冲的响应.
Integral equations are constructed first according to the continuity conditions of fields in the aperture. Then the main components of electric fields in rectangular cavity are expressed with the inner product of the electric field in the aperture and the orthonormal bases, which is obtained from the integral equation using the method of integral operator expansion. Finally, the response, of a rectangular cavity with a small aperture to a typical electromagnetic pulse is calculated using IFFT.
