完全導体円板上の垂直微小ダイポール波源からの放射電磁界の解析方法

摘要

An analytical method of diffracted electromagnetic field by a circular disk of perfect conductor is discussed for dipole incidence, when the source is polarized perpendicular to the disk. Expanding a Hertz vector of diffracted field by eigen functions of a Helmholtz equation for circular disk, an infinite linear matrix equation for expansion coefficients is obtained, as shown by Y. Nomura and S. Inawashiro[1J for plane wave incidence. An approach for a derivation of the expressions for γhs. of the equation are discussed.%完全導体円板に対して，垂直方法を向いた電気的微小ダイポールを波源とする，電磁波の散乱問題の解析方法を示した.さらに，波源が円板に近い場合に収束が速い級数にョる表現式を導出した.数値計算にョる具体的な電磁界分布の評価は今後の課題である.
