摘要

本文提出了一种超薄双频超材料吸收体，用于x波段。所提出的吸收器的单元电池由两个交叉椭圆组成，周围是压印在接地的FR4介电衬底上的u形元件。所设计的吸波器厚度$\boldsymbol{\lambda}/53，\ \boldsymbol{\lambda}$对应于谐振频率最低的波长。由于单晶胞的对称设计，所设计的结构是极化无效的。所提出的吸收体是紧凑的尺寸，非常低的厚度，似乎是潜在的指导双波段应用。TM和TE模式响应的斜入射也是稳定的。

Polarization Independent Ultrathin Dual-Band Metamaterial Absorber for X-Band Applications

This paper, an ultrathin dual-band Metamaterial absorber have been proposed for X-band applications. The unit cell of proposed absorber composed of two cross ellipses surrounded by U-shaped element imprinted on grounded FR4 dielectric substrate. The designed absorber has thickness $\boldsymbol{\lambda}/53,\ \boldsymbol{\lambda}$ corresponds to wavelength of lowest resonant frequency. The designed structure is polarization ineffective due to symmetrical design of unit cell. The presented absorber is compact in size, very low thickness and seems to be potentially instructive for dual-band applications. The oblique incidence for both TM and TE mode response is also steady.
