Electrical characterizations of paraelectric BST thin films up to 1 THz : realization of microwave phase shifters

Gabriel Vélu, Gregory Houzet, Ludovic Burgnies, Jean-Claude Carru, Aurélien Marteau, Karine Blary, Didier Lippens, Patrick Mounaix, Marc Tondusson, Edwin Nguema Agnandji

BST thin films have been deposited with a sol-gel technique on 4cm 2 sapphire. Electrical characterizations have been performed in a very large frequency range. From 1 kHz to 500 GHz, the dielectric constant ϵ r is around 300 with quasi no frequency dispersion. In the 500 GHz to 1 THz range, the…

Two types of modes in finite size one-dimensional coaxial photonic crystals : general rules and experimental evidence

E.H. El Boudouti, Y. El Hassouani, Bahram Djafari-Rouhani, H. Aynaou

We demonstrate analytically and experimentally the existence and behavior of two types of modes in finite size one-dimensional coaxial photonic crystals made of N cells with vanishing magnetic field on both sides. We highlight the existence of N−1 confined modes in each band and one mode by gap…

Frequency-time MMSE equalizer for BER enhancement of MC-CDMA systems over mulipath fading channel

F. Bouasria, Ali Djebbari, Merahi Bouziani, Jean-Michel Rouvaen, Abdelmalik Taleb-Ahmed

This paper examines the performance of a multicarrier CDMA system over multipath fading channel. Due to the dispersive nature of the mobile communications channels, Multi-Carrier Code Division Multiple Access (MC-CDMA) signals will be affected by Inter Channel Interference (ICI), Inter Symbol…
