Reconfigurable designs for EIT in solid state plasma metamaterials with multiple transmission windows

A reconfigurable metamaterial analog electromagnettically induced transparency like (EIT-like) effect is theoretically and numerically demonstrated in this paper. The unit cell is composed of a stimulated circular loop element and an unstimulated arc slot element, which are both constructed by semiconductor. The proposed designs can realize a continuously tunable EIT-like effect in a broad frequency range, while the number of EIT-like transmission windows can be configured by increasing the number of arc slots.
