Reduction of mutual coupling between strip dipole antennas at terahertz frequencies with an elliptically shaped graphene monolayer
In this paper, we propose to use the concept of mantle cloaking in order to decrease the mutual coupling between strip dipole antennas at low terahertz frequencies. Here, we show that by wrapping the antennas with a properly tuned elliptically shaped graphene monolayer, the electromagnetic interaction between the antennas can be suppressed considerably, and the radiation patterns can be restored. The tunability of graphene with respect to its chemical potential allows us to reduce the mutual coupling between the antennas over a range of frequencies.
