This contribution presents the results of investigations performed on monolayer graphene field effect transis-tor-based (GFET-based) terahertz detectors. We have implemented three different types of planar antennae: a bow-tie, a bow-tie with transmis

This work presents an approach to distinguish the thermoelectric detection mechanism from the resistive mixing or plasma wave rectification in graphene FET THz detectors. Numerical full-wave simulations validate the asymmetric feeding of the existing
