将棱边单元与时域中心差分相结合，建立了求解麦克斯韦方程组的时域有限元方法。这种方法解决了电场作为空间和时间的矢量函数在有限的圆柱形腔的几何形状的任意几何形状。使用生长因子技术和Z变换对该方法进行了两次稳定性分析。此外，还研究了该方法的计算复杂度。通过对各种微波谐振腔的谐振频率的研究，验证了该方法的有效性。
A finite-element time-domain (FETD) method for solving Maxwell's equations was developed by combining prism-based edge elements with central differencing in the time domain. This method solves for the electric field as a vector function of space and time in finite cylindrical cavity geometries of arbitrary geometry. Two stability analyses of this method are performed using the growth factor technique and the Z-transform. Furthermore, the computational complexity of the present approach is also investigated, This method has been implemented and its validity tested by studying the resonant frequencies of various microwave cavities.
