Contribution

It introduces a novel microwave setup with a varicap for periodic driving and provides experimental validation of sideband structures predicted by semiclassical theory.

Findings

Observed specific sideband shapes in the linear regime

Experimental data agrees with theoretical semiclassical models

Demonstrated control of sideband structures through driving signals

Abstract

A realisation of a periodically driven microwave system is presented. The principal element of the scheme is a variable capacity, i.e. a varicap, introduced as an element of the resonant circuit. Sideband structures corresponding to different driving signals, have been measured experimentally. In the linear regime we observed sideband structures with specific shapes. The main peculiarities of these shapes can be explained within a semiclassical approximation. A good agreement between experimental data and theoretical expectations has been found.
