Larges bandes interdites phononiques dans une structure de piliers coniques déposés sur un substrat piézoélectrique

Abdelali Mrabti, Mourad Oudich, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani, Abdelkrim Talbi, Jérémy Streque, Yu Du, Ali Soltani, Philippe Pernod

Dans ce papier nous étudions l'existence et le comportement des bandes interdites absolues en dessous de la ligne du son du substrat dans une structure phononique. Le cristal phononique est constitué de piliers coniques de Nickel déposés sur un substrat de Niobate de Lithium (LiNbO3). Nous...

Iterative soft-Kalman channel estimation for fast time-varying MIMO-OFDM channels

E.P. Simon, M.A. Khalighi

This letter addresses the problem of channel estimation in fast time-varying frequency selective channels. Considering orthogonal frequency division multiplexing in a multipleinput multiple-output system, we perform soft-Kalman filtering for channel estimation in conjunction with soft-interference...

Low loss microstrip transmission-lines using cyclic olefin copolymer COC-substrate for sub-THz and THz applications

Abdallah Chahadih, Magdalena Chudzik, Israel Arnedo, Abbas Ghaddar, Ivan Arregui, Fernando Teberio, Aintzane Lujambio, Miguel A. G. Laso, Txema Lopetegi, Tahsin Akalin

We describe low loss microstrip transmission line with compact coplanar waveguide transitions for sub-terahertz application. The conducting transmission line is fabricated on the surface of a thin cyclic olefin copolymer dielectric layer. A vector network analyzer (VNA) has been used to obtain the...

Confinement and losses of THz planar Goubau lines fabricated on a thin silicon substrate

Abdallah Chahadih, Mokhtar Zehar, Abbas Ghaddar, S. Kaya, Ibrahim Türer, Gabriel Moreno, Y. Zapart, Tahsin Akalin

Low loss broad band transmission lines are of great interest for terahertz applications. To overcome high losses, Planar Goubau Lines (PGL) have been designed and fabricated on high resistivity silicon substrate. The measured loss level is typically 1dB/mm around 250GHz. The transitions are also...
