Abstract
Description
電磁波の可視化技術として、特許文献1(特開2011-53055号公報)及び特許文献2(特開2000-214198号公報)がある。特許文献1には、「直交するX軸及びY軸上に配置した2対の4つのアンテナ、或いは1つのアンテナを共用した3つのアンテナと、測定対象領域の風景を写す画像カメラと、アンテナ信号を検出する検出部と、信号処理及び解析部と、表示部とを有する。信号処理及び解析部は、X軸及びY軸上に配置したアンテナ対に到達する電磁波のそれぞれの時間差Δtx、Δtyを測定して、この各Δtx、Δtyの値により、測定対象領域の範囲を分割した分割領域を特定する。表示部は、特定された分割領域を、画像カメラが写した風景に重畳して表示する。」と記載されている。
また、特許文献2には、「磁界プローブ4を被測定対象の近傍で移動させるための移動部19と、磁界検出部6と、磁界プローブ4の指向性が最大の方向を検出すべき磁界の方向に向けるための校正をおこなう校正部とを有する。校正部は、磁界プローブの向きを変化させるプローブ変位部27と、校正用磁界発生部5と、プローブ変位部の動作を制御する制御部7とを備える。制御部7は、プローブ変位部27を動作させて校正用磁界内で磁界プローブ4の向きを変化させ、そのときの前記磁界検出部6の出力から磁界プローブ4の指向性の向きを検出する。」と記載されている。
上述したように、特許文献1~2の技術では、複数ある電磁ノイズの発生源をリアルタイムに可視化することが困難である。
そこで、本発明では、複数存在する電磁ノイズの発生源を遠方界、近傍界の双方において装置の動作環境においてリアルタイムに可視化することのできる電磁波可視化装置を提供する。
図5に示すように、板状の誘電体20の表面である第1層に、金属パッチ21が周期状に配置されている。詳しくは、複数の金属パッチ21が行方向(横方向)と列方向(縦方向)に、碁盤の目状に配置されている。各金属パッチ21は、可変抵抗31により接続されている。そして、各金属パッチ21の中央には、それぞれ、後述するビア22が設けられている。
このとき、抵抗25を波動インピーダンスと同様の377Ωとすれば、空間とセンサ部2のインピーダンスが整合され、電磁波が反射せずセンサ部2に電磁波のエネルギーが吸収される。
はじめに電磁波の遠方界を測定する場合について説明する。電磁波の遠方界を測定は図2の構成で測定を行う。例えば測定対象6のノイズ源7から発生した電磁波61を、射出方向分離部である電磁波レンズ1で分離、つまり、電磁波の到来方向に応じて電磁波レンズ1から射出する電磁波の射出方向を変え、センサ部2へ入射させる。センサ部2は可変抵抗を377Ωとし、電磁波レンズ1を透過した電磁波が入射してエネルギーが誘起されたセンサが、誘起されたエネルギーの大きさに応じた強さの検知信号を出力する。
