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…

Novel SuperLattice Plasmon Mode in a Grating of 2D Electron Strips
V. M. Muravev, K. R. Dzhikirba, A. A. Zabolotnykh +7
We investigate GaAs/AlGaAs heterostructure membranes with a metasurface made up of a grating of two-dimensional electron system (2DES) strips. Experiments have revealed a strong pl…

Discovery of Slot Plasma Excitations in a AlGaN/GaN Plasmonic Crystal
A. R. Khisameeva, A. Shuvaev, I. M. Moiseenko +6
We experimentally investigate the terahertz spectrum of plasma excitations in a plasmonic crystal based on AlGaN/GaN two-dimensional electron system (2DES). While screened plasmon…
