Enhancing the modulation depth of a dynamic terahertz metasurface by integrating into an asymmetric Fabry-Pérot cavity
Source abstract
Abstract
The modulation capability of a terahertz dynamic metasurface was enhanced by integrating it with an asymmetric Fabry-Pérot cavity. The dynamic metasurface consists of split ring resonators combined with high frequency metal semiconductor metal varactors. Integrating the above dynamic metasurface into an asymmetric Fabry-Pérot cavity results in a modulation performance improvement of up to 3.3 times. An analytical model based on transmission line theory illustrates the modulation enhancement mechanism, and provide guidelines for designing dynamic metamaterial devices based on cavity structures.
