摘要 采用时域有限差分(FDTD)法对超宽带(UWB)脉冲和圆柱腔体连接缝隙的耦合过程进行研究,通过不同脉宽UWB脉冲对腔体耦合电场的时域和频域分析,观察共振效应和增强效应等现象,讨论了圆柱腔体连接缝隙的耦合电场特性和带有连接缝隙腔体的谐振特性。 Finite differential time domain（FDTD） method is used to study the coupling process of ultra wideband（UWB） pulse entering a cylindrical cavity connecting slot.Through time and frequency domain analysis of coupling electric field for different UWB pulse widths,resonant effect and enhancement effect observation,the coupling characteristics of electric field of a cylindrical cavity connecting slot and the resonance of the cavity with a connecting slot are discussed.
