Application of the FDTD method to determine complex permittivity of dielectric materials at microwave frequencies using a rectangular waveguide

J. Terhzaz, H. Ammor, A. Assir, A. Mamouni

A new measurement technique is presented to determine the complex permittivity of a dielectric material. The dielectric sample is loaded in a short-circuited rectangular waveguide. The reflection coefficient of the waveguide is measured by Network analyzer and calculated as a function of the…

In situ epitaxial surface passivation of GaAlN/GaN HEMT heterostructures grown by LP-MOCVD

Marie-Antoinette Di Forte-Poisson, Nicolas Sarazin, M. Magis, Maurice Tordjman, Erwan Morvan, Raphaël Aubry, J. Di Persio, Bertrand Grimbert

This paper reports on in situ passivation studies of GaAlN/GaN High electron mobility transistors (HEMT) structures grown by low-pressure metalorganic vapour phase epitaxy (LP-MOVPE) on sapphire and silicon carbide substrates. GaN, GaAlN, AlN and AlN/GaN superlattice (SL) layers have been deposited…

Selective filtering of confined optical waves in a straight waveguide coupled to a lateral stub

Yan Pennec, Maxime Beaugeois, Bahram Djafari-Rouhani, Abdellatif Akjouj, Jerome O. Vasseur, L. Dobrzynski, Jean-Pierre Vilcot, Mohamed Bouazaoui, J.P. Vigneron

We report numerical simulations, based on a finite difference time domain (FDTD) method, of light propagation in two-dimensional semiconductor micro optical waveguides coupled to one or several lateral stubs. The incident wave which is of transverse magnetic polarization (TM) is either…
