Optimization of a tunable piezoelectric resonator using phononic crystals with periodic electrical boundary conditions

Marie-Fraise Ponge, Bertrand Dubus, Christian Granger, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

Piezoelectric phononic crystals with periodic short-circuit conditions exhibit Bragg band gaps. They are used to design a Fabry-Perot cavity. The design of the device enables a modification of cavity length by a spatial shift of electrical boundary conditions. The resonator is thus tunable and a...

Modeling and de-embedding the interferometric scanning microwave microscopy by means of dopant profile calibration

L. Michalas, Fei Wang, Charlene Brillard, Nicolas Chevalier, Jean-Michel Hartmann, Romolo Marcelli, Didier Theron

This paper presents the full modeling and a methodology for de-embedding the interferometric scanning microwave microscopy measurements by means of dopant profile calibration. A Si calibration sample with different boron-doping level areas is used to that end. The analysis of the experimentally...

Optically-pumped continuous-wave terahertz sources

Philipp Latzel, Fabio Pavanello, Emilien Peytavit, Mohammed Zaknoune, Guillaume Ducournau, X. Wallart, Jean-Francois Lampin

Recently we have improved the efficiency and the output power of our optically pumped continuous-wave THz sources. These sources are based on the beating of two laser lines in a wide bandwidth photodetector. Its intrinsic nonlinear behaviour is used to produce a beatnote at the frequency difference...

Tunability of Bragg band gaps in one-dimensional piezoelectric phononic crystals using external capacitances

Sebastien Degraeve, Christian Granger, Bertrand Dubus, Jerome O. Vasseur, Mai Pham Thi, Anne-Christine Hladky

A one-dimensional stack of identical piezoelectric rods is investigated. The device exhibits a band gap related to electrical boundary condition. A separate control of the central frequency and of the width of the band gap is performed by an electrical boundary condition involving two different...

Wave propagation in functionally graded piezoelectric rods with rectangular cross-section

J.G. Yu, Zhang Bo, Jean-Etienne Lefebvre, C. Zhang

For the purpose of design and optimization of functionally graded piezoelectric material (FGPM) transducers, wave propagation in FGPM structures has received much attention in the past twenty years. But research focused essentially on semi-infinite structures and one-dimensional structures, i.e.,...

Analysis of a Phononic Crystal Constituted of Piezoelectric Layers Using Electrical Impedance Measurement

S.A. Mansoura, Pierre Marechal, Bruno Morvan, Bertrand Dubus

Active materials are investigated as a tuning possibility for phononic crystals. Electromechanical properties of piezoelectric materials electrical and mechanical variables are coupled. Thus, the propagation properties of elastic waves can be tuned using electrical impedance load connected to the...

Cancellation Technique for CW Ground Penetrating Radar Applications

S. Nounouh, Kamel Haddadi, T. Lasri

An adjustable canceller based on microwave interferometry is proposed for ground penetrating radar applications. This canceller, built up with a power divider and an impedance tuner, is integrated in a monostatic continuous wave (CW) radar in order to improve its measurement sensitivity. A set of...
