摘要: 本文分別用FD-TD(時(shí)域有限差分)法和不均勻劃分TLM(傳輸線矩陣)法計(jì)算標(biāo)準(zhǔn)TEM小室的諧振頻率。在FD-TD法的計(jì)算中,提出一種新的磁邊界條件的處理方法,節(jié)省了計(jì)算量,給出了大量未曾發(fā)表過的標(biāo)準(zhǔn)TEM小室內(nèi)諧振頻率的計(jì)量結(jié)果。在不均勻劃分TLM方法的計(jì)算中,按小室的自然結(jié)構(gòu)不均勻的劃分小室內(nèi)的傳播空間,也達(dá)到了節(jié)省計(jì)算量的目的。最后,對(duì)這兩種方法和計(jì)算結(jié)果進(jìn)行了比較。給出了若干結(jié)論。

Abstract: The resonant frequencies of the NBS TEM cell have been calculated by the Finite-Difference Time-Domain (FD-TD) and irregularly graded Ttansmis-sion-Line Matrix(TLM) methods. In the calculating process by the FD-TD method a novel processing method for the magnetic wall boundary conditions is developed with which it is possible to treat only one eighth of the whole cell domain to calculate the resonant frequencies. As a result, additional useful resonant frequency data are listed. In the TLM meth ,d, the prop... -
