A novel reconfigurable electromagnetically induced transparency based on solid state plasma

This paper presents a reconfigurable metamaterial and simulates the electromagnetically induced transparency (EIT) effect. The unit cell is composed of a cutwire (CW), a split ring resonator (SRR), and rectangular patches which are made up of solid-state GaAs-PIN cell. The interference between The CW and SRR produces a transparency window such as a special phenomenon of quantum optics called EIT. A reconfigurable EIT can be achieved by changing the split gap of SRR and the transparency window has flexible reconfigurability. This scheme which is constructed by solid state plasma (SSP) metamaterial provides an effective way to realize reconfigurable compact slow-light devices design.
