Space-Time Modulation: Principles and Applications
Sajjad Taravati, Ahmed A. Kishk
This paper overviews the principles, theoretical analysis and numerical simulation of STM media and their applications in communication systems. We first present a global perspecti…
Nonreciprocal Electromagnetic Scattering from a Periodically Space-Time Modulated Slab and Application to a Quasisonic Isolator
Sajjad Taravati, Nima Chamanara, Christophe Caloz
Scattering of obliquely incident electromagnetic waves from periodically space-time modulated slabs is investigated. It is shown that such structures operate as nonreciprocal harmo…
Nonreciprocal Nongyrotropic Magnetless Metasurface
Sajjad Taravati, Bakhtiar A. Khan, Shulabh Gupta +2
We introduce a nonreciprocal nongyrotropic magnetless metasurface. In contrast to previous nonreciprocal structures, this metasurface does not require a biasing magnet, and is ther…
Mixer-Duplexer-Antenna Leaky-Wave System Based on Periodic Space-Time Modulation
Sajjad Taravati, Christophe Caloz
We present a mixer-duplexer-antenna leaky-wave system based on periodic space-time modulation. This system operates as a full transceiver, where the upconversion and downconversion…
