Switchable SAW Resonators and Ladder Filters Composed of Interdigitated Combs

R. Alcorta Galván, Charles Croënne, Bertrand Dubus, B. Loiseaux, E. Eustache, M. Bertrand, A.-C. Hladky-Hennion

This work presents the development of switchable SAW resonators fabricated on a LiNbO3 substrate, which use the Electrical Bragg Bandgap concept to control the resonance frequency. The modification of the electrical condition of electrode arrays shifts their bandgap center frequency which in turn…

Enhanced Fluid Characterization with a Cantilever Microbeaman System Excited by an Embedded Electroactive Source

Victory Elias, Emmanuel Dubois, Nikolay Smagin, Frédéric Rivart, Alex Vercampt, Georges Nassar

When there is a variation in fluid concentration at the free end of a microcantilever, this phenomenon can be utilized in applications such as chemical analysis, biological testing, pharmaceutical screenings, and environmental monitoring. This paper introduces a novel sensor based on a silicon…

Ab Initio Study of the Crystalline Structure of HgS under Low and High Pressure

Ahmed Amine Aidouni, Abdelkader Aissat, Mounir Ould-Mohamed, Mohamed El Amine Benamar, Samuel Dupont, Jean Pierre Vilcot

This study analyzes the lattice dynamics of HgS under various pressures using ab initio self-consistent calculations based on the plane-wave method (PW) and generalized gradient approximation (GGA). The static study, performed by enthalpy calculations, predicts that the transition from the cinnabar…
