Static-to-dynamic field conversion with time-varying media
Mario Junior Mencagli, Dimitrios L. Sounas, Mathias Fink +1
In this Letter, we theoretically demonstrate that a uniform static electric field distribution can be partially converted to radiation fields when a portion of the medium undergoes…
Electromagnetic Isolation Induced by Time-Varying Metasurfaces: Non-Reciprocal Bragg Grating
Davide Ramaccia, Dimitrios L. Sounas, Angelica V. Marini +2
In this letter, we propose a magnet-less non-reciprocal isolating system based on time-varying metasurfaces. Two parallel time-varying metasurfaces, one for frequency up-conversion…
Phase-Induced Frequency Conversion and Doppler Effect with Time-Modulated Metasurfaces
Davide Ramaccia, Dimitrios L. Sounas, Andrea Alu' +2
Metasurfaces consisting of electrically thin and densely packed planar arrays of subwavelength elements enable an unprecedented control of the impinging electromagnetic fields. Spa…
