전자파는 매질을 지나면서 투과, 흡수 및 반사가 일어나며, 이러한 현상들은 매질의 종류와 형상 등에 영향을 받으며, 매질의 전자기적 성질에 따라 흡수체와 반사체로 구분될 수 있으며 이러한 성질을 이용하여, 세계의 각 나라에서는 레이더의 허상제거나 레이더 교란등 주로 군사적 목적으로 전자파흡수체를 개발해왔다. 최근 군사적 목적 뿐만 아니라 전자파장애방지용 플라스틱이나 유리제품, 고주파 흡수용 석고보드등 일상생활에 사용되는 제품의 개발이 활발하였고,Electromagnetic waves are transmitted, absorbed, and reflected as they pass through the medium. These phenomena are affected by the type and shape of the medium, and can be classified into absorbers and reflectors according to the electromagnetic properties of the medium. Each country has developed electromagnetic wave absorbers mainly for military purposes, such as radar imagery or radar disturbances. Recently, the development of products used in daily life such as plastic or glass products for preventing electromagnetic interference, gypsum board for high frequency absorption, as well as military purposes, has been active.

최근에는 고전압 송전선에서 유도된 초극저주파 등과 같은 다양한 전자파가 인체에 미치는 영향 및 차례기술에 대한 연구가 있어왔다.Recently, there have been studies on the effects of various electromagnetic waves on the human body, such as ultra-low frequency induced in high-voltage transmission lines, and a turn technology.
