 note = {本論文では、数値電磁界解析手法であるFDTD法に基づき、パルス状の電圧波を始端に印加した際の高周波領域における導体波形伝搬モードについて検討した。その結果、TEM及びTMモードの波形伝搬モードの変化は、空気とは異なる比誘電率を有する絶縁体で覆われた被覆導体の始端及び終端で発生し、導体の中心ではTEMモードのみ現れることが明らかとなった。その変化は導体中心からの離隔距離に依存する。, This paper investigates the characteristics of wave propagation modes on a conductor in high frequencies when a pulse-like voltage is applied to the sending end, based on a finite-difference time-domain (FDTD) method of a numerical electromagnetic analysis. It is found that transition of the wave propagation mode between TEM and TM occurs at the sending and receiving ends on an insulated conductor of which the relative permittivity ε[i] ≠ of the insulator is different from that of air, i.e. ε[i] ≠ 1, while only the TEM mode appears in the middle of the conductor. The transition is dependent on the distance from the conductor center., 抄録中の「[i]」は下付き文字, application/pdf},
