| 摘 要： | 通过经典电磁学理论推导,提出一种完全吸收入射平面电磁波的电阻薄膜-介质层-全反射导体膜结构。该结构要求电阻薄膜与真空波阻抗匹配,电阻薄膜背面衬以λ/4厚度的无损耗介质,介质的底部放置全反射导体膜,即可保证全吸收入射电磁波,这对红外辐射计和隐身材料均适用,为此类特殊功能材料的研究提供依据。

| Abstract: | In this paper a two-layer film structure with a resistive film-dielectric layer-total reflection film is provided to completely absorb the incident planely electromagnetic wave by the classical electromagnetic theory.The structure requires that the resistive film and the vacuum wave impedance match,the resistive film's back be lined with lossless media of a quarter wavelength thickness,and the total reflection conductor film should be placed at the bottom of the media.The structure ensures total absorption of the incident electromagnetic wave and can be used for infrared radiometers and stealth materials.The model provides theoretical basis for researching such special functional materials. |
