パルスTM平面波の導体棒配列による散乱の数値解析: 平行平板線路モデルとそのTLMによる解析

摘要

著者らは互いに平行な無限長導体棒列による平面電磁波（TM波）の散乱を解析してきたが，これの応用として，何本かの導体棒で支えられた平行平板線路内での散乱問題に発展させた．これは，導体棒に垂直な2枚の導体平面で囲まれた空間では，無限長の場合と同じく2次元解析で与えられるからその正当性は理解できる．本論文では，導体棒で支えられた平行平板導体板間を伝搬する波の時間応答を，伝送線路モデルで代用し解析した一例を紹介する．%EMC researchers can recognize that near fields formed by scattering from some objects are very important. To know the near fields or electromagnetic distributions, the authors have proposed a new effective calculation method: 'thin wire approximations'. And they have expanded the application of the method to the analyses of the field distribution between parallel metal plates supported by several conductive pillars. The validity of the expansion could be understood since both cases are 2-dimensional problems. In this paper, the transient scattering responses of conductive pillars for pulsed plane wave incidence are analyzed using the transmission line model (TLM).
