摘要：

The design of a broadband tunable absorber is proposed based on a thin vanadium dioxide metasurface, which is composed of a simple array of vanadium dioxide and a bottom gold film. When the conductivity of vanadium dioxide is equal to 2000 Omega(-1) cm(-1) simulated absorptance exceeds 90% with 71% bandwidth from 0.47 to 0.99 THz and full width at half maximum is 98% from 0.354 to 1.036 THz with center frequency of 0.695 THz. Simulated results show that absorptance peak can be tuned from 5% to 100% when the conductivity changes continually from 10 Omega(-1) cm(-1) to 2000 Omega(-1) cm(-1). The designed absorber may have useful applications in terahertz spectrum such as energy harvesting, thermal emitter, and sensing.
