A VO2 film-based multifunctional metasurface in the terahertz band
文献摘要：
We proposed a multifunctional terahertz metasurface based on a double L-shaped pattern and a vanadium dioxide[VO2]film separated by polyimide.When the VO2 film is an insulator,a dual-band electromagnetically induced transparency effect is obtained,and the physical mechanism is investigated based on the current distribution and "two-particle" model.When the VO2 film is a metal,a dual-band linear-to-circular polarization converter,in which the y-polarized linear wave can be effec-tively converted to left-handed circularly polarized[LCP]and right-handed circularly polarized simultaneously in different bands,can be achieved.By arranging the metal pattern rotating 30°,a multifunctional antenna can be obtained.When the VO2 is an insulator,the radiation of the LCP wave is divided into four beams,with two beams reflected and two beams transmitted.When the VO2 is in the metallic state,we can only get the co-polarized reflected wave with a 21° angle.Moreover,in our design,the VO2 film does not need lithography to obtain certain patterns,which improves the convenience of fabrication and experiment.Our design opens a new way for the development of multifunctional terahertz devices and has potential applications in the terahertz communication field.
