Abstract:A wideband, polarization-insensitive and wide-angle metamaterial absorber on double layer resistive film is presented. A unit cell of the absorber consists of a ring resistance film, a substrate, ring resistance film, a substrate and a metal backboard. The simulations and analyses of electromagnetic absorbing properties of this absorber are performed by the finite-difference time-domain method. The simulated reflection and absorption indicate that the absorption of this absorber is greater than 90% in a frequency range of 11.5–20.3 GHz. The simulated absorptions under different polarization conditions and incident angles indicate that this absorber is polarization-insensitive and of wide-angle. And the simulated influence of structure parameters indicate that the absorption of this absorber originates mainly from the absorbing mechanism of circuit resonance, the operation frequency range and bandwidth can also be adjusted by the design of the substrate thickness, the resistance value of resistance film and the width of resistance film, where this absorber are strongest and the absorption band is widest.
