摘要
电磁场时域计算方法由于一次计算可以获得目标的时域响应,结合傅里叶变换得到宽带信息等的优势越来越受到关注.本文介绍了近年来时域有限差分(finite-difference time-domain,FDTD)法和时域有限元(finite element time-domain,FETD)无条件稳定算法方面的研究进展以及FETD算法的更新方案--时域非连续伽辽金(discontinuous Galerkin time-domain,DGTD)方法的新进展.
The time-domain computation of electromagnetic field has attracted more and more attention because it can obtain the time-domain response of the target by one calculation, and combines the advantages of Fourier transform to obtain broadband information. In this paper, the research progress of finite-difference time-domain and unconditional stability algorithm of finite element time-domain in recent years is introduced. In addition, the new development of discontinuous Galerkin method time-domain, which is an updated scheme of finite element method time-domain, is introduced.
