Antenna-Mixer-Amplifier Transceiver Based on Space-Time Surface Waves
Antenna-Mixer-Amplifier Transceiver Based on Space-Time Surface Waves
We propose a front-end transceiver, i.e., an antenna-mixer-amplifier, by leveraging unique properties of space-wave to surface wave transformation in a space-time periodic medium. Such functionality is offered by space-time surface waves corresponding to complex space-time wave vectors in a subluminal space-time medium. The proposed structure provides pure frequency up/down-conversions supported by weak undesired higher order time harmonics. In contrast to other recently proposed space-time mixers, a large frequency up-/down conversion ratio and amplification is achievable. In addition, the structure does not require progressive energy transition between the space-time modulation and the incident wave, and thus, possesses a subwavelength thickness.

Abstract
We propose a front-end transceiver, i.e., an antenna-mixer-amplifier, by leveraging unique properties of space-wave to surface wave transformation in a space-time periodic medium. Such functionality is offered by space-time surface waves corresponding to complex space-time wave vectors in a subluminal space-time medium. The proposed structure provides pure frequency up/down-conversions supported by weak undesired higher order time harmonics. In contrast to other recently proposed space-time mixers, a large frequency up-/down conversion ratio and amplification is achievable. In addition, the structure does not require progressive energy transition between the space-time modulation and the incident wave, and thus, possesses a subwavelength thickness.
