Abstract
= 4.7 THz). As the ambient temperature changes, the THz smart switch can achieve active switching of the absorption from 2% to 99.9% and the transmission from 89% to 0%. It is worth noting that the THz smart switch can also realize the active switching of absorption and transmission over a wide-angle range. This study provides important insights for the design of active controllable devices and also offers a new concept for the design of THz multi-functional devices.
