Phase Coded Costas Signals for Ambiguity Function Improvement and Grating lobes Suppression

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Atika Rivenq

In this paper, a novel radar signal is proposed. It is based on a modification of Costas signals obtained by increasing the frequency separation of Costas frequency hops beyond the orthogonality condition. Indeed, Costas codes are well known for their good Range-Doppler properties. Their…

High spectral purity microwave and terahertz oscillator

Gwennaël Danion, Goulc'Hen Loas, Ludovic Frein, Cyril Hamel, Anthony Carré, Steve Bouhier, Marc Vallet, Marc Brunel, Antoine Rolland, Mehdi Alouini, François Bondu, Alexandre Beck, Guillaume Ducournau, Mohamed Zaknoune, Christophe Coinon, Xavier Wallart, Emilien Peytavit, Tahsin Akalin, Jean-Francois Lampin, Frédéric Cleva, Jean-Pierre Coulon, Mourad Merzougui, Alain Brillet, Gregoire Pillet, Loïc Morvan, Ghaya Baili, Jérôme Bourderionnet

We report on the design of an ultra stable microwave/THz oscillator and on the realization and the characterization of its laser source. The tunable oscillator is expected to show below -150 dB rad2/Hz phase instability at an offset frequency of 10 kHz for a 30 GHz carrier frequency, as well as 18…

Characteristics of the surface microstructures in thick InGaN layers on GaN

Y. El Gmili, G. Orsal, K. Pantzas, A. Ahaitouf, T. Moudakir, S. Gautier, G. Patriarche, David Troadec, Jean-Paul Salvestrini, A. Ougazzaden

This paper focuses on a comparative study of optical, morphological, microstructural and microcompositional properties of typical InGaN samples which exhibit V-defects but also two additional surface defects features, referred to as inclusion#1 (Ic1) and inclusion#2 (Ic2). HR-XRD, AFM, SEM, STEM…

Coherent tunnelling across a quantum point contact in the quantum Hall regime

F. Martins, S. Faniel, B. Rosenow, Hermann Sellier, Serge Huant, M. G. Pala, L. Desplanque, X. Wallart, Vincent Bayot, B. Hackens

The unique properties of quantum Hall devices arise from the ideal one-dimensional edge states that form in a two-dimensional electron system at high magnetic field. Tunnelling between edge states across a quantum point contact (QPC) has already revealed rich physics, like fractionally charged…
