In this paper, we show that a MoS2thin film formed from a mixture of pristine MoS2 monolayers and few-layer flakes deposited on a coplanar waveguide (CPW) is acting as an electrically tunable microwavematerial. In this respect, we have seen that up to 30 GHz, the transmission and reflection parameters of the CPW depend on the applied voltage. We have extracted from the measurements an equivalent circuit and have observed that the surface resistance is dependent on the DC applied voltage, as in the case of other two-dimensional materials such as graphene. So, the device is acting as a tunable matching network via an applied DC voltage.
