Graphene Enables Tunable Microwave Antenna
Electrically tunable mid-infrared antennas based on VO2 investigated based on the integration of optical antennas with tunable materials, such as photoconductive semi-conductors (10, 11), liquid crystals (12), phase-change materials (13–15), and two-dimensional materials such as graphene (16). Vanadium dioxide (VO 2) is a promising candidate for tunable optical devices. It exhibits a dramatic ... Cross-slot nano-antenna with graphene coat for bio-sensing ... In this article, we are designing a conventional cross-slot antenna for bio optical application and in addition we have used a graphene coat for improving the antenna transmittance. At last, the silicon dioxide chains are placed on the graphene layer at aperture placement. We improve antenna's quality factor by adding these new layers.
