94-GHz load pull measurements of SiGe HBT by extracting output power density in W-band

Issam Hasnaoui, Elodie Canderle, Pascal Chevalier, Daniel Gloria, Christophe Gaquière

In this paper, we present a W-Band load pull test bench used to improve a characterization of Silicon Germanium Heterojunction Bipolar Transistor (SiGe HBT). High accuracy is obtained in Load-pull measurements at 94 GHz on lastgeneration SiGe HBTs by extracting the input reflection hot Sparameter (...

Terahertz electromagnetic response of random-bond metal mesh

Yuichiro Okui, Keisuke Takano, Hideaki Kitahara, Abdallah Chahadih, Abbas Ghaddar, Tahsin Akalin, Masanori Hangyou

A metal mesh shows Drude-like metallic effective permittivity dispersion. By cutting all wires of the mesh, the metal mesh becomes a metal cross array and shows Lorentz-like effective permittivity dispersion. We prepared the samples of metal mesh with random cut systematically and measured the...

Legendre and Laguerre polynomial approach for modeling of wave propagation in layered magneto-electro-elastic media

Olivier Bou Matar, Noura Gasmi, Huan Zhou, M. Goueygou, Abdelkrim Talbi

A numerical method to compute propagation constants and mode shapes of elastic waves in layered piezoelectric-piezomagnetic composites, potentially deposited on a substrate, is described. The basic feature of the method is the expansion of particle displacement, stress fields, electric and magnetic...

Improvement of the oxidation interface in an AlGaAs/AlxOy waveguide structure by using a GaAs/AlAs superlattice

J.Y. Song, S. Bouchoule, G. Patriarche, E. Galopin, A.M. Yacomotti, E. Cambril, Q.G. Kou, David Troadec, J.J. He, J.C. Harmand

The wet oxidation from the mesa sidewalls of AlGaAs/GaAs epitaxial structures is investigated in details. In addition to the intended lateral oxidation of the Al-rich buried layer, we observe a parasitic vertical oxidation of the adjacent layers of lower Al content. This vertical oxidation produces...

Metamaterial-inspired bandpass filter for the terahertz Goubau line

Ali Karami Horestani, Withawat Withayachumnankul, Christophe Fumeaux, Derek Abbott, Tahsin Akalin

Recently, it has been shown that a single wire Goubau line that supports surface wave propagation can be used as an effective terahertz waveguide with low attenuation and low dispersion. In order to fully exploit Goubau lines in terahertz systems, for example for communication applications,...
