Abstract

　【目的】この発明は、比誘電率が１０以上であり、分子イオン、荷電粒子を含み、磁界変動によって変位電流を生じ、磁界変動の伝搬損失が電界変動の伝搬損失より比較的に小さい物質中において、磁界アンテナ，磁流アンテナから放射される磁界変動，磁流変動によって伝搬する磁力波信号が、電界アンテナから放射される電界変動によって伝搬する電磁波信号に比較して低損失であり、長距離の伝搬特性を有することを利用した磁力波通信装置である。【構成】磁力波通信装置２１からは１００ｋＨｚから３０ＧＨｚまでの周波数帯で比較的に広い帯域幅の磁力波信号をループアンテナ２１３によって海水中に放射し、磁力波信号を磁力波通信装置２２に接続されたループアンテナ２２３によって受信する。磁力波信号が海水中を低損失でかつ長距離を伝搬するので、ループアンテナ２１３と２２３の間で磁力波信号を低損失で効率よく送受信することができる。
