Graphene Plasmonic Antenna
Nano-Antenna Resonance in Terahertz Domain
Microscopic antennas made from atom-thick graphene sheets that resonate at terahertz frequencies, enabling wireless communications between micro-robots and chips.
Technical Explanation
Conventional copper antennas cannot be miniaturized below millimeters without suffering massive resistive losses and impedance mismatches. Graphene Plasmonic Antennas leverage the unique electronic properties of two-dimensional carbon graphene. Graphene's slow-wave plasmonic resonance allows an antenna measuring only a few micrometers to radiate efficiently in the 1 to 5 Terahertz band, unlocking wireless communications for medical micro-robots inside the bloodstream.
Key Functions
- Atom-thick two-dimensional carbon graphene sheets resonating efficiently in the THz band
- Microscopic antenna footprints (1 to 10 micrometers) suitable for micro-robotic integration
- Plasmonic wave velocity 100x slower than the speed of light, enabling extreme miniaturization
- Dynamically tunable resonant frequency modulated by applying electrostatic gate voltages
- Enabling high-speed wireless interconnects between individual micro-cores on computer processors
