Title (EN) META-MATERIAL DEVICE AND ANTENNA DEVICE
(FR) DISPOSITIF EN MÉTAMATÉRIAU ET DISPOSITIF D'ANTENNE
(JA) メタマテリアル装置及びアンテナ装置
Abstract:
(EN) This meta-material device is provided with at least one unit resonator (1). The unit resonator (1) is provided with a resonance element (21), and a pair of reflection elements (22). The resonance element (21) has a strip shape having first and second end parts, has a path that does not include a parallel circuit section in which current flows simultaneously in reverse directions between the first and second end parts, and has substantially zero effective magnetic permeability. Each of the pair of reflection elements (22) is connected respectively to the first and second end parts of the resonance element, and the impedance when each reflection element (22) is viewed from the resonance element (21) becomes substantially zero. The unit resonator (1) operates as a zero-order resonator.
(FR) L'invention concerne un dispositif en métamatériau comprenant au moins un résonateur unitaire (1). Le résonateur unitaire (1) comprend un élément de résonance (21) et une paire d'éléments de réflexion (22). L'élément de résonance (21) a une forme de bande ayant des première et seconde parties d'extrémité, a un trajet qui ne comprend pas une section de circuit parallèle dans laquelle le courant circule simultanément dans des directions inverses entre les première et seconde parties d'extrémité, et a une perméabilité magnétique efficace sensiblement nulle. Chacun de la paire d'éléments de réflexion (22) est connecté respectivement aux première et seconde parties d'extrémité de l'élément de résonance, et l'impédance lorsque chaque élément de réflexion (22) est visualisé à partir de l'élément de résonance (21) devient sensiblement nulle. Le résonateur unitaire (1) fonctionne comme un résonateur d'ordre zéro.
(JA) メタマテリアル装置は、少なくとも1つの単位共振器(1)を備える。単位共振器(1)は、共振素子(21)と、一対の反射素子(22)とを備える。共振素子(21)は、第1及び第2の端部を有するストリップ形状を有し、第1及び第2の端部の間で電流が同時に逆向きに流れる並列回路部分を含まない経路を有し、かつ、実質的にゼロの実効透磁率を有する。一対の反射素子(22)は、共振素子の第1及び第2の端部にそれぞれ接続され、共振素子(21)から各反射素子(22)を見たときのインピーダンスが実質的にゼロになる。単位共振器(1)は0次共振器として動作する。
