Acoustic microscope based on magneto-elastic wave phase conjugator

Andrey Brysev, Leonid Krutyansky, Philippe Pernod, Vladimir Preobrazhensky

Acoustic C-scan imaging (acoustic microscopy) by means of supercritical parametric wave phase conjugation (WPC) is studied experimentally. A phase conjugator based on a magneto-acoustic active material is used for compensating phase distortions introduced by solid and polymer aberration layers…

Elaboration and characterization of PNZT thin films deposited on silicon by RF cathodic sputtering

T. Haccart, Eric Cattan, Denis Remiens

Pb(Zr,Ti)O3 (PZT) and Pb(Zr,Ti,Nb)O3 (PNZT) thin films have been grown on platinized silicon substrates by RF magnetron sputtering followed by a post-annealing treatment. The niobium, Nb, concentration varied from 1 to 7 at.% by increment of 1 at.% The effects of the Nb introduction on the PZT…

Monolithic Microwave Integrated GaAs Electromagnetically-Coupled Antenna

Marjorie Grzeskowiak, Jean Vindevoghel

Monolithic antenna on GaAs to be used in miniature active sensors is presented. After a first study of technological processes and the characterisation of various substrates in K-band, the feasibility of an antenna, operating in K-band, electromagnetically-coupled and integrated on GaAs by…

Conception of integrated polymer antennas for characterisation of dielectric properties

Marjorie Grzeskowiak, Philippe Descamps, Jean Vindevoghel

To design microstrip antennas, we have to know the relative permittivity and losses of the antenna substrate. In the case of polymers, these electrical properties are given at 1 MHz by the constructor and are not the same ones at other frequencies. We decide to take this problem back to front and…
