This "Cited by" count includes citations to the following articles in Scholar. ... A tunable microwave slot antenna based on graphene. ... MoS2 thin films as ... Microwave synthesis 'zaps' graphene to perfection A quick and efficient way to produce single-layer graphene using microwaves and ionic liquids has been found by RIKEN researchers. Takuzo Aida from the RIKEN Center for Emergent Matter Science and colleagues from across Japan theorized that using everyday microwave ovens might improve graphene synthesis. A graphene solution for microwave interference -- ScienceDaily A single layer of graphene can absorb up to 25% of incident microwave radiation, which is a lot for a one atom-thick material. With a multilayer graphene/PMMA arrangement, the absorption rises to 50%. Low-cost RF antenna printed with graphene ink — could soon ... To create the graphene ink-based RF antenna, the researchers mixed graphene flakes with a solvent. Typically, the next step is to add a binder like ethyl cellulose to help the ink stick — it also helps the graphene conduct electricity better than binder-free ink.

We present terahertz (THz) detectors based on top-gated graphene field effect transistors (GFETs) with integrated split bow-tie antennas. The GFETs were fabricated using graphene grown by chemical vapor deposition (CVD). The THz detectors are capable of room-temperature rectification of a 0.6 THz signal and achieve a maximum optical responsivity better than 14 V/W and minimum optical noise ... Development of Graphene Based Tapered Slot Antennas for ... which is realized by adjusting a bias or gate voltage. This tunable property of graphene conductivity is utilized to tune the antenna resonance frequency, which in turn paves the way to design frequency reconfigurable antennas in microwave and THz regimes. Graphene based antennas could provide several Optically Transparent Microwave Polarizer Based On Quasi ... A tunable microwave slot antenna based on graphene.

A Microwave Field Effect Transistor Based on Graphene In this way, microwave switches can be implemented based on the specific charge carrier transport in graphene. The maximum stable gain of the transistor isroom temperature [4], and (iii) tunable input impedances around 50 Ω, specific for RF applications, in microwave devices based on graphene [5]... Graphene antenna - Wikipedia A graphene antenna is a proposed high-frequency antenna based on graphene, a one atom thick two dimensional carbon crystal, that would enhance radio communications. The unique structure of graphene would enable these enhancements.
