損失性導体である生体表面における高周波電磁波の導波，伝送を用いた医用通信システムとして人体センサーと送信アンテナによる高周波信号伝送が検討されている．この医用システムでは，生体表面上の人体センサーを送信源として，生体表面を境界とする導波路を通して，他の生体表面上の受信アンテナまでの伝送路を第1伝送経路とし，受信点を第2送信点として第2の伝送路は通常のペアケーブルなどによる情報通信路とする．ここでは，人体表面である導電性生体表面における電磁界境界における電磁波固有導波特性を明らかにしている．また，著者が検討してきている複雑電磁波境界値問題に適用可能な等角写像法とGreen関数を用いた積分方程式によって損失性の曲り導電性生体表面境界における電磁波導波特性を解析している．人体表面の電磁波導波を用いた臨床的通信システムの基礎を示している．%High frequency signal transmissions using human body sensors and transmission antennas have been studied, as biomedical communication systems of high frequency electromagnetic guided waves on biological surfaces of lossy conducting media. In these biomedical systems, the first section of transmission is consisting of human body sensor and transmission antenna on the body surface that is signal transmission source, and receive terminal antenna that is receiver, through transmission waveguide with body surface boundary of body media. The second section of transmission is consisting of transmission source output that is receiver of the first section, and usual information transmission line of pair cables.rnIn this paper, electromagnetic eigen characteristics of high frequency fields on conducting bio-medical body surface that is boundary surface of waveguide are discussed. By using conformal mapping method and integral equation with Green's function that can be applied to analysis of complicated electromagnetic field boundary problems developed by the author, electromagnetic guided characteristics of electromagnetic fields on curved conducting biological body surfaces are investigated. Fundamental properties of medical application of high frequency signal transmission on human body surfaces are shown.
