摘要：
In this paper, we present the design and simulation of a compound absorber based on metamaterial and magnetic material. The absorber is composed of ferrite layer, metal patch, dielectric layer and metal backboard. Utilizing two different structures of metamaterial absorbers, and arranging them in a special way, an 8.5 dB RCS reduction from 300MHz to 2 GHz is finally achieved, and the maximum reduction of RCS is 13 dB. The total thickness of the absorber is 4.5mm that is approximately 1/133 of the working wavelength. Additionally, the absorber can strongly absorb the obliquely incident electromagnetic wave for both transverse electric and transverse magnetic polarizations, even at 40 degrees angle of incidence.
