▎ 摘　　要

In this letter, we propose to use the concept of the mantle cloaking method in order to reduce the mutual coupling between strip dipole antennas at low-terahertz (THz) frequencies. Here, we show that by covering each antenna with an elliptically shaped graphene monolayer, the electromagnetic interaction between the antennas can be suppressed drastically. The material properties of the graphene monolayer are properly tuned to provide the required surface reactance that leads to the restoration of the radiation patterns of the antennas as if they were isolated and uncoupled. 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.
