Wideband and high-order microwave vortex-beam launcher based on spoof surface plasmon polaritons
Abstract The electromagnetic vortex carrying orbital angular momentum (OAM), which is first studied at optical frequency, has begun to attract widespread attention in the field of radio-frequency/microwave. However, for the OAM mode generated by traditional single antennas, there are problems such a...
