Tunable massive and acoustic plasmons in two-dimensional plasmonic crystals
I. V. Gorbenko, P. A. Gusikhin, V. Yu. Kachorovskii +1
We theoretically investigate dispersion of plasma waves propagating in a lateral plasmonic crystal based on a two-dimensional electron system with grating gates. Two specific confi…

Ratchet effect in lateral plasmonic crystal: Giant enhancement due to interference of "bright" and "dark" modes
I. V. Gorbenko, S. O. Potashin, V. Yu. Kachorovskii
We develop a theory of the ratchet effect in a lateral plasmonic crystal (LPC) formed by a two dimensional electron gas under a periodic dual-grating gate. The system is driven by…

Lateral plasmonic crystals: Tunability, dark modes, and weak-to-strong coupling transition
I. V. Gorbenko, V. Yu. Kachorovskii
We study transmission of the terahertz radiation through a two-dimensional electron gas with a concentration controlled by grating gate electrodes. Voltage applied to these electro…
