Abstract

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.
