Abstract

We propose and study a time-varying metasurface for parametric amplification of electromagnetic waves. We found that our subwavelength thin metasurface can provide amplification of up to 10 dB and analysed its stability. The proposed amplification principle can be used for electromagnetic waves in the radio, microwave and subterahertz range and is limited by the properties of modern varactor diodes.
