In this paper, we propose a novel gravity-tailored absorber to achieve two different absorption peaks at two different frequencies, whose improvement is based on the traditional sandwich structure. It is unusual that two dug grooves inside are filled with the liquid dielectrics. Since existing the gravity field, rotating this absorber in the xy plane will make the absorption peak change. In addition, this gravity-tailored absorber has a good stability of the incidence angle. The discussion of the power flow, the electric field, and structure parameters are also given to explain the physical mechanism. Compared with the existing manners of regulation, this regulation of presented absorber might be more convenient to achieve.

基于重力场调节的对角不敏感的超材料吸收体

在本文中,我们提出了一种新颖的重力定制吸收器,可以在两个不同的频率上实现两个不同的吸收峰,其改进是基于传统的夹心结构。不寻常的是,内部的两个挖沟充满了液体电介质。由于存在重力场,在xy平面上旋转此吸收器将使吸收峰发生变化。另外,该重力定制吸收器具有良好的入射角稳定性。还讨论了功率流,电场和结构参数,以解释其物理机理。与现有的调节方式相比,提出的吸收器的这种调节可能更方便实现。
