Holographic Beamforming
Holographic Radio & Dynamic Metasurface Antennas (DMA)
Ultra-thin, energy-efficient continuous antenna apertures that synthesize arbitrary electromagnetic radiation patterns using holographic interference principles.
Technical Explanation
Conventional beamforming requires complex, power-hungry phase shifters and digital-to-analog converters behind each antenna element. Holographic Beamforming employs continuous-aperture Dynamic Metasurface Antennas (DMA). By adjusting the electromagnetic resonance of metamaterial dipoles excited by a guided reference wave, the surface generates holographic interference patterns in the air, creating arbitrary 3D beam shapes, multi-beam projections, and orbital angular momentum vortexes with minimal power dissipation.
Key Functions
- Continuous spatial aperture synthesizing near-continuous electromagnetic current distributions
- Elimination of bulky, expensive phase-shifting hardware components
- Generating arbitrary 3D beam shapes and deep radiation nulls to silence interferers
- Ultra-thin form factors (<2 mm) suitable for vehicle roofs, drone wings, and window glass
- Extreme energy efficiency enabling high-power Sub-THz transmissions without overheating
