Generalized Conductivity Modeling and Selective Harmonic Amplification in Time-Modulated Graphene Cavities
Ioannis M. Koutzoglou, Stamatios Amanatiadis, Nikolaos V. Kantartzis +1
The selective harmonic enhancement in cavities formed by stacks of time-modulated graphene sheets and a reflecting boundary is investigated. A semi-analytic framework based on an o…

Transient States to Control the Electromagnetic Response of Space-time Dispersive Media
Pablo H. Zapata-Cano, Salvador Moreno-RodrÃguez, Stamatios Amanatiadis +3
In this paper, we study the dynamic formation of transients when plane waves impinge on a dispersive slab that abruptly changes its electrical properties in time. The time-varying…
