Optical Isolation based on Space-time Engineered Asymmetric Photonic Bandgaps
Nima Chamanara, Sajjad Taravati, Zoé-Lise Deck-Léger +1
Nonreciprocal electromagnetic devices play an important role in modern optical and microwave technologies. Conventional methods for realizing such systems are incompatible with int…
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…
Enhanced Bandwidth and Diversity in Real-Time Analog Signal Processing (R-ASP) using Nonuniform C-section Phasers
Sajjad Taravati, Shulabh Gupta, Qingfeng Zhang +1
We show that a continuously nonuniform coupled line C-section phaser, as the limiting case of the step discontinuous coupled-line multisection commensurate and non-commensurate pha…
