Design of Artificial Metamaterial Absorber Based on Stacking Method

A millimeter-sized artificial periodic structure material is successfully simulated, showing the characteristics of a thin geometric scale, broadband response, and high wave absorption. The structural units are stacked with metal circles, notched circular rings, dielectric material. design similar to quasi-two-dimensional planar maintains while reducing number layers in stack. In addition, electromagnetic model this microstructure established study its S-parameters suction properties through simulations. Numerical results reveal that when incident vertically, absorption over 90% frequency range 14.4-14.8 GHz 15.4-20.6 GHz. absorber features same for different polarization states.
