Query: Reconfigurable-Metasurface-Aided Multi-State Generalized
  Polarization-Space Modulation for Next-Generation Wireless Communications   We propose a low-cost reconfigurable metasurface transmitter to implement
generalized polarization-space modulation (GPSM) that has been proposed for
next-generation wireless communications. Unlike conventional multiple-input
multiple-output GPSM, our electromagnetically-compliant, reduced form-factor
design using Barium-Strontium-Titanate film yields more than two polarization
states. Full-wave simulations show our optimized design achieves 0.08-0.95
polarization conversion ratio with 5% bandwidth at 28 GHz and bit error rates
comparable or better than conventional systems.
