Switchable and Tunable Terahertz Metamaterial Based on Vanadium Dioxide and Photosensitive Silicon
A switchable and tunable terahertz (THz) metamaterial based on photosensitive silicon and Vanadium dioxide (VO2) was proposed. By using a finite-difference time-domain (FDTD) method, the transmission and reflective properties of the metamaterial were ...

Transformation of subradiant state to superradiant state in a thick resonant medium
The propagation of a step pulse through a thick resonant absorber with homogeneously broadened absorption line is considered. It is shown that a specific subradiant state is naturally developed in the absorber due to the formation of the spatial domains ...
