Abstract

We propose the design of a magnet-free non-reciprocal leaky-wave antenna at terahertz (THz) frequencies based on a spatiotemporally modulated graphene monolayer. Spatiotemporal modulation is achieved through time-varying voltages applied over a set of gate electrodes beneath the graphene monolayer, providing ample freedom to impart the required effective linear momentum to the supported mode. The nonreciprocal radiation properties of the antenna, in terms of transmission/reception gain patterns and frequency conversion, are discussed in detail. This class of graphene plasmonic devices may pave the way to the development of fully planar THz transceivers and advanced imaging and sensing systems.
