Abstract

Akind of controllable metamaterial absorbing structure is presented in this paper, both transmission coefficient and single radar cross section (RCS) are electrically controlled. This structure is composed from split ring resonators (SRRs) and metallic wire arrays including pin diodes, pin diodes are periodically inserted at these wire arrays discontinuous, and they can be either in an on state or in an off state depending on the voltage to realize the electronic control. We use the metallic wave-guides theory, ANSOFT HFSS, high impedance surface (HIS), radiation boundary conditions, and a master-slave (M/S) relationship between each of the periodic boundary conditions (PBC's) pairs, to simulate the transmission coefficient and single radar cross section (RCS), and simulation proves that this method and technology can absorb vertical incident microwave. This is very useful for getting zero-reflected power and better aircraft stealth performance in the future.
