Polarization-Controlled Metamaterial Absorber with Extremely Bandwidth and Wide Incidence Angle

In this paper, a three-dimensional metamaterial structure absorber has been analyzed and discussed. The unit of the absorber is composed of nine different size resistive films which are placed vertically on a metal plate. The proposed metamaterial absorber can achieved the perfect absorption for different polarized waves by rotating around the center axis. The simulated results also show that the 3D absorber has the properties of extremely bandwidth, exhibiting the absorption with above 90 % for TM or TE wave from 20 to 55 GHz. In addition, the mechanism of different absorption between TE and TM mode is also discussed based on the E-field and power loss density distributions. The proposed absorber has potential application in polarization detectors, polarizer, sensor, and so on.
