Doubly coded Costas signals for grating lobes mitigation

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Atika Rivenq

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

Dynamics of confined cavity modes in a phononic crystal slab investigated by in situ time-resolved experiments

R. Marchal, Olga Boyko-Kazymyrenko, Bernard Bonello, Jinfeng Zhao, Laurent Belliard, Mourad Oudich, Yan Pennec, Bahram Djafari-Rouhani

The confinement of elastic waves within a single defect in a phononic crystal slab is investigated both experimentally and theoretically. The structure is formed by a honeycomb lattice of air holes in a silicon plate with one hole missing in its center. The frequencies and polarizations of the…

Microwave On/Off ratio enhancement of GaAs photoconductive switches at nanometer scale

Charlotte Tripon-Canseliet, Salim Faci, Antoine Pagies, Vincent Magnin, Stéphane Formont, Didier Decoster, Jean Chazelas

This paper reports on performances enhancement of photoconductive switches in term of On/Off ratio and insertion losses. The optimization parameters on which the research has been focused are gap dimensions reduction to nanometer scale. The device characterization results up to a microwave…
