An elliptical SRR low-profile multiband antenna-backed AMC for wireless applications and satellite communications

Z. Mordi, Z. Hamouda, S. Chenaoui, M. Lagha, T. Lasri

Abstract This paper presents a low-profile, triple-band elliptical coplanar waveguide-fed antenna designed using the split-ring resonator technique. An artificial magnetic conductor with three zero-phases of the reflection coefficient is incorporated as a reflector to improve the antenna gain. The…

Corneal endothelial dysfunction treatments: Recent advances in non-invasive treatment strategies

Nataliia Gnyliukh, Rabah Boukherroub, Sabine Szunerits

The corneal endothelium plays an essential role in the maintenance of a healthy vision. However, in contrast to epithelial cells with high proliferation rates and a turnover lifespan of six to seven days that allows maintenance of constant cell density and high control of cell adhesion, human…

Electricity-driven selectivity in the photocatalytic oxidation of methane to carbon monoxide with liquid gallium-semiconductor composite

My Nghe Tran, Alina Skorynina, Ahmed Addad, Ali Fadel, Karima Ben Tayeb, Lydia Karmazin, Louis Thomas, Massimo Corda, Yevkeni Wisse, Evgeny Vovk, Andrei Khodakov, Bruno Grandidier, Vitaly Ordomsky

Metal co-catalysts in oxide semiconductors are essential to enhance photocatalytic reaction, but the selectivity is often low due to the conversion of the target molecules as more reactive in comparison with the reagents. Here, we explore the influence of electricity on the activity and selectivity…

Room-temperature, continuous-wave terahertz generation in free-space with an intersubband mid-infrared photomixer

Quyang Lin, Jean-François Lampin, Guillaume Ducournau, Sylvie Lepilliet, Hua Li, Emilien Peytavit, Stefano Barbieri

We demonstrate a terahertz photomixer pumped by mid-infrared photons at a wavelength of 10 μm. The device is based on a dual-antenna architecture, in which a two-dimensional array of mid-infrared patch-antenna resonators is connected to the electrodes of a log-spiral terahertz antenna. By…
