Plasmonic Transceiver
Graphene-Based Terahertz Waveguide Transceiver
Nanoscale transceivers exploiting Surface Plasmon Polaritons (SPP) on graphene sheets to transmit and detect terahertz radiation at microscopic scales.
Technical Explanation
Traditional metallic antennas become extremely lossy and inefficient when scaled down to terahertz wavelengths. Plasmonic Transceivers utilize graphene sheets that support Surface Plasmon Polaritons (SPP)—coupled oscillations of electromagnetic waves and electrons. These surface waves have wavelengths up to 100 times shorter than free-space waves, allowing microscopic graphene nano-antennas (a few micrometers in size) to radiate and detect THz waves with high efficiency.
Key Functions
- Surface Plasmon Polariton (SPP) wave excitation on two-dimensional graphene layers
- Microscopic antenna form factors (micrometers in size) radiating in the THz band
- Extreme tunability achieved by adjusting graphene's chemical potential via gate voltage
- Enabling intra-chip and inter-chip wireless communication inside high-performance processors
- Biocompatible nano-sensors capable of wireless telemetry inside biological tissues
