Abstract

This work is devoted to the numerical simulation of electromagnetic characteristics of multiresonant metamaterials consisting of microresonators made of vanadium dioxide and silicon designed to operate in the infrared range. The dependences of the spectral response on metamaterial geometric parameters and reflection coefficient contrast during semiconductor–metal transition in vanadium dioxide are analyzed. It has been shown that the electromagnetic response in the infrared range is determined by Mie resonances, plasmon and quasi-waveguide resonance. It has been established that hybrid metamaterials on a silicon substrate can achieve higher reflection coefficient switching contrast in a wider spectrum compared to similar structures on quartz substrates. Spectral dependencies of switching power threshold for metamaterials on quartz and silicon substrates have been determined.
