Coherent perfect absorption in a coupled electric-magnetic-resonator system
We proved numerically and experimentally that coherent perfect absorption (CPA) can be achieved in a coupled electromagnetic induced transparency (EIT) system. Unit cell of EIT system consists of a “T-type” cut wire (CW) electric resonator and a pair of double split rings (DSRs) magnetic resonator, placed on the same side of microstrip line. Intermediate coupling between electric and magnetic resonators and their respectively appropriate loss lead to the CPA, where an ideal Parity-time (PT) symmetry is also achieved. These results provide a potential way for designing absorption devices.
