Detection of subterahertz and terahertz radiation by high electron mobility GaN/AlGaN transistors in the 0.2-2.5 THz frequency range (much higher than the cutoff frequency of the transistors) is reported. Experiments were performed in the temperature range 4-300 K For the lowest temperatures, a…

High emission and detection efficiency of terahertz beam with heavy-ion-irradiated InP material excited at 0.8 µm

Patrick Mounaix, Marc Tondusson, Nicolas Chimot, Juliette Mangeney, Karine Blary, Jean-Francois Lampin

The performance from a high-energy Br+-irradiated InP photoconductive antenna excited at 800 nm has been investigated. The ionic irradiation into InP reduces significantly the lifetime of photo-carriers in the substrate material down to 1.4 ps without the requirement of an epitaxial layer growth.…

Electromagnetic wave propagation in quasi-one-dimensional comb-like structures made up of dissipative negative-phase-velocity materials

Gregorio Hernandez-Cocoletzi, L. Dobrzynski, Bahram Djafari-Rouhani, Housni Al-Wahsh, Driss Bria

We study the propagation of electromagnetic waves in infinite lines with grafted finite lines in a frequency regime, where the grafted lines have negative phase velocity. The physical properties of such a structure with negative phase velocity materials have not been investigated before, to the…
