  • On-chip terahertz topological leaky-wave antennas based on valley photonic crystals achieve beam scanning over 75% of the three-dimensional solid angle. The time-reversal-symmetric topological leaky-wave antenna further enables the simultaneous demonstration of real-time high-definition television streaming and 24 Gbps directional wireless data transmission in opposite directions.
