这项工作提出了一个高精度和高效率的方法计算的电磁谐振频率及其相关模式的空腔。所提出的技术包括一个高阶不连续Galerkin时域求解器结合信号处理算法提取的频率内容。该方法能够将域的CAD边界表示。数值结果表明，将精确的边界表示结果在一个改进的收敛速度，一个现象，以前没有报道。在二维和三维的几个数值例子表明，所提出的技术充满非色散或色散介质的空腔的潜力。
This work presents a highly accurate and efficient methodology for the computation of electromagnetic resonant frequencies and their associated modes in cavities. The proposed technique consists of a high–order discontinuous Galerkin time-domain solver combined with a signal processing algorithm for extracting the frequency content. The methodology is capable of incorporating the CAD boundary representation of the domain. The numerical results demonstrate that incorporating the exact boundary representation results in a improved convergence rate, a phenomenon that has not been previously reported. Several numerical examples in two and three dimensions show the potential of the proposed technique for cavities filled with non-dispersive or dispersive media.
