Bragg band gaps tunability in an homogeneous piezoelectric rod with periodic electrical boundary conditions

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

An homogeneous piezoelectric rod is shown to exhibit Bragg band gaps when an electrical boundary condition is applied periodically with the help of metallic electrodes. An analytical model is developed which formulation depends on the applied electric boundary condition and reveals that Bragg band...

Inkjet coplanar square monopole on flexible substrate for 60-GHz applications

Aimeric Bisognin, Julien Thielleux, Wei Wei, Diane Titz, Fabien Ferrero, Patrice Brachat, Gilles Jacquemod, Henri Happy, Cyril Luxey

In this letter, the design, fabrication, and measurement of a 60-GHz printed antenna with inkjet technology over a flexible substrate is presented. The antenna is a coplanar square monopole with omnidirectional radiation characteristics. We especially measured a 68% total efficiency and a maximum...

Millimeter-wave in situ tuner : an efficient solution to extract the noise parameters of SiGe HBTs in the whole 130-170 GHz range

Marina Deng, Laurent Poulain, Daniel Gloria, Thomas Quémerais, Pascal Chevalier, Sylvie Lepilliet, Francois Danneville, Gilles Dambrine

SiGe HBT noise parameters ( , and ) are for the first time extracted in the entire 130 - 170 GHz frequency range. This achievement is realized using a D-band on-chip source-pull system, which includes an impedance tuner integrated with the transistor under test. On-wafer noise power measurements on...

[Review] Generation of transversal envelope soliton in polymeric and wooden rods

M. de Billy, Anne-Christine Hladky

This paper is concerned with the probing of the transversal envelope solitons propagation in circular waveguides when a set of requirements (non-linearity and dispersion) are fulfilled in the waveguide and balanced. The basic idea is to analyze the shape of an acoustic pulse after it has traveled...

Enhancement of thermoelectric power factor in NaxCoO2/Au multilayers

Xiaohui Zhao, Haifeng Wang, Shufang Wang, El Hadj Dogheche, Jianglong Wang, Guangsheng Fu

NaxCoO2/Au thin film multilayers, with a thickness of the Au layer of 0.5–12 nm, have been fabricated on c-Al2O3 by post annealing of the CoO/Au thin film multilayers in Na vapor at high temperature in air. X-ray diffraction measurements revealed that the resulting NaxCoO2 layer was c-axis oriented...

Scale effects induced by imperfect interfaces in nanomaterials transport properties

Fabio Pavanello, F. Manca, Pier Luca Palla, Evelyne Lampin, Fabrizio Cleri, Stefano Giordano

One of the crucial factors governing the physical properties of nanomaterials is the complex behavior of the interfaces[1]. While at the macroscopic level their specific role is usually neglected, in nanostructured systems the properties of the contact between phases have to be carefully defined....

Application of nodal discontinuous Galerkin finite element method for 2D nonlinear elastic wave propagation

Yifeng Li, Jingjing Wang, Olivier Bou Matar

In order to solve the elastic wave equation in heterogeneous media with arbitrary high order accuracy in space on unstructured meshes, a nodal Discontinuous Galerkin Finite Element Method (DG-FEM) is presented, which combines the geometrical flexibility of the Finite Element Method and strongly...
