抄録

<p>A metasurface which can realize switching between transmission and reflection modes by changing temperature is proposed. The metasurface consists of a dielectric layer and two metal layers with an extremely low profile. At low temperature, it can convert the incident circularly polarized wave into an orthogonal polarization wave; while at high temperature, the incident circularly polarized wave will be completely reflected and keep the same polarization. By appropriately arranging the unit cell structure, a full space focusing lens is realized at 1.0THz. This work provides a new idea for designing full-space metasurfaces, which has great potential value in the fields of reconfigurable and dynamically controllable device design.</p>
