Description
Summary:The analysis of a substrate-integrated cavity with a time-modulated graphene layer located at its aperture is realized in the present work focusing on the frequency up-conversion characteristics. The cavity is designed with a rectangular profile, while metallic-coated via holes are drilled into the substrate for field confinement. The radiation at the resonance frequencies is facilitated using an aperture slot that is filled with graphene. Its surface conductivity varies in time through the effective adjustment of the electric bias field permitting the successful generation of higher frequencies.
