Detection of chemical damage in concrete using ultrasound

S. Ould Naffa, Marc Goueygou, Bogdan Piwakowski, François Buyle-Bodin

This research deals with a non-destructive method for characterizing the degraded cover of concrete structures using high-frequency ultrasound (0.5–1 MHz). Although such a frequency range is unusual in civil engineering, it is well suited to the kind of defect to be detected, as it corresponds to a…

Process and realization of a three dimensional gold electroplated antenna on a flexible epoxy film for wireless micromotion system

Philippe Basset, Andreas Kaiser, Dominique Collard, Lionel Buchaillot

The process and realization of a light and low resistive antenna for wireless communications by inductive coupling at 13.56 MHz is presented. The antenna is realized on an insulated substrate made of SU-8 resist in order to prevent the losses due to eddy currents from occurring and to strongly…

Assessment of broadhand ultrasonic attenuation measurements in inhomogeneous media

Marc Goueygou, Bogdan Piwakowski, S. Ould Naffa, François Buyle-Bodin

In this paper, we address the problem of evaluating the acoustic attenuation of “difficult” media, i.e. highly attenuating and scattering media. In a broadband, through transmission setup, the signals acquired from such media are characterized by a poor signal-to-noise ratio. Therefore, an accurate…

Imperfect Return Path Effects on RLCG Model of Single and Coupled Interconnects: Propagation Delay, Rise Time and Crosstalk Prediction

Jean-François Legier, Erick Paleczny, K. El Bouazzati, Denis Deschacht, Fabrice Huret

If we take a look at the latest ITRS 2001 edition[1], we will realize the number and difficulties of technical challenges the semiconductor industry must solve. Traditional scaling which has been at the basis of the semi conductor industry during these last three decades is indeed beginning to show…

Architecture level center frequency drift compensation method for micro-mechanical filters used in IF stages of wireless telecommunication receivers

Olivier Billoint, Dimitri Galayko, Bernard Legrand, Andreas Kaiser

A prototype of a 433.92 MHz RF receiver using a micro-mechanical resonator as channel-selection filter in the 2nd IF stage has been realized (94.5 kHz center frequency, 20 Hz bandwidth). A novel approach is used for managing the temperature drift of the center frequency of the micro-mechanical…
