摘要
应用非正交网格时域有限差分算法，模拟了在高斯脉冲和高斯脉冲调制正弦波激励下有激励孔微波谐振腔的激励和谐振过程，分析了谐振频率。模拟结果表明：在微波谐振腔内，激发出了最接近脉冲激励源主频的若干个谐振态。
A nonorthogonal finite difference time domain algorithm is used to model the excitation and resonance processes of a circular resonator with an excitation aperture,where a Gaussian pulse and a sine modulated Gaussian pulse are used as excitation pulses.Resonant frequencies are analysed by the method of fast Fourier transform.The calculated results agree well with theoretical analyses.Simulation results show that several resonant frequencies nearest to the main ferquency of the excitation pulse are excited.
