Frequency Conversion Characteristics of Spatiotemporal Josephson Metasurfaces for Quantum Applications
Sajjad Taravati
This presentation explores the various characteristics of a nonreciprocal, frequency-converting Josephson metasurface operating at millikelvin temperatures. Leveraging the unique p…
Temporal Bragg Gratings: Broadband Reconfigurable Parametric Amplifiers
Sajjad Taravati
This paper introduces temporal Bragg gratings as a new class of broadband, reconfigurable parametric amplifiers. We present a comprehensive investigation of power amplification in…
Designing Space-Time Metamaterials: The Central Role of Dispersion Engineering
Sajjad Taravati
Space-time metamaterials are redefining wave engineering by enabling fully dynamic four-dimensional control of electromagnetic fields, allowing simultaneous manipulation of frequen…
Finite-Difference Time-Domain Simulation of Wave Transmission Through Space-Time-Varying Media
Sajjad Taravati, Ahmed A Kishk, George V Eleftheriades
A comprehensive study on the Finite Difference Time Domain (FDTD) numerical modelling of space- and time-varying media is presented. We investigate the dynamic behavior of oblique…
Dynamic Modulation Yields One-Way Beam Splitting
Sajjad Taravati, Ahmed A. Kishk
This article demonstrates the realization of an extraordinary beam splitter based on nonreciprocal and synchronized photonic transitions in obliquely illuminated space-time-modulat…
