Abstract:
(EN) An electromagnetic wave absorber (1a) is provided with a first layer (10) and a conductive layer (20). The first layer (10) is a dielectric layer or a magnetic body layer. The conductive layer (20) is provided to at least one side of the first layer. The product of the Young's modulus of the first layer (10) and the thickness of the first layer (10) is 0.1-1000 MPa·mm. The specific dielectric constant of the first layer (10) is 1-10.
(FR) La présente invention concerne un absorbeur d'ondes électromagnétiques (1a) qui est pourvu d'une première couche (10) et d'une couche conductrice (20). La première couche (10) est une couche diélectrique ou une couche de corps magnétique. La couche conductrice (20) est disposée sur au moins un côté de la première couche. Le produit du module de Young de la première couche (10) et de l'épaisseur de la première couche (10) est de 0,1 à 1000 MPa · mm. La constante diélectrique spécifique de la première couche (10) est de 1 à 10.
(JA) 電磁波吸収体(1a)は、第一層(10)と、導電層(20)とを備える。第一層(10)は、誘電体層又は磁性体層である。導電層(20)は、第一層の少なくとも片側に設けられている。第一層(10)のヤング率と第一層(10)の厚みとの積は、0.1~1000MPa・mmである。第一層(10)の比誘電率は、1~10である。
