- Abstract
In this work, a quadruple-band dielectric metamaterial absorber (MMA) was proposed and studied, which is composed of eight cuboid dielectric particles and a metallic ground plate. When electromagnetic wave is incident on the dielectric particles, dielectric particles act as resonators and produce abundant resonant modes, which can result in perfect absorption. In simulation, four absorption peaks are observed at 9.13, 9.62, 10.0 and 10.46 GHz with 88%, 89%, 100% and 96%, respectively. By adjusting geometry parameters of the dielectric particles, dielectric MMAs with different bands can be obtained. Further investigation shows that the absorption peaks can be changed by increasing the permittivity of the dielectric. Based on the designing technique of using simple cuboid dielectric particles directly acting as resonator, this work provides a simple method to construct multiband all-dielectric MMA.
