Piezoelectric nonlinearity and frequency dispersion of the direct piezoelectric response of BiFeO3 ceramics

We report on the frequency and stress dependence of the direct piezoelectric d33 coefficient in BiFeO3 ceramics. The measurements reveal considerable piezoelectric nonlinearity, i.e., dependence of d33 on the amplitude of the dynamic stress. The nonlinear ...

Fully Passivated AlInN/GaN HEMTs With f(T)/f(MAX) of 205/220 GHz

Nicolas Grandjean, Jean-François Carlin

We report the fabrication and characterization of 30-nm-gate fully passivated AlInN/GaN high-electron mobility transistors (HEMTs) with cutoff frequencies f(T) and f(MAX) simultaneously exceeding 200 GHz at a given bias point. The current gain cutoff frequ ...

A Compact Single-Layer Dual-Band Microstrip Antenna for Satellite Applications

Seyyed Hussein Seyyed Esfahlani

In this letter, a compact single-layer, single-feed, dual-frequency microstrip antenna with a high frequency ratio is proposed. This antenna has a broadside and symmetrical radiation patterns suitable for space-borne applications. The prototype was fabrica ...

Cavitation influence on hydroacoustic resonance in pipe

François Avellan, Christophe Nicolet, Sébastien Alligné, Nicolas Ruchonnet

In pipe systems, pressure and flow fluctuations below cutoff frequency propagate as plane waves along pipes. Depending on the pipe length and propagation velocity, resonance leading to high amplitude pressure fluctuation may occur. At low pressure, cavitat ...

Filter Bank Fusion frames

Amina Chebira

In this paper we characterize and construct novel oversampled filter banks implementing fusion frames. A fusion frame is a sequence of orthogonal projection operators whose sum can be inverted in a numerically stable way. When properly designed, fusion fra ...

Impact of pump depletion on the determination of the Brillouin gain frequency in distributed fiber sensors

Luc Thévenaz, Stella Foaleng Mafang, Jie Lin

The energy transfer between the two interacting optical waves in a distributed sensor based on stimulated Brillouin scattering can lead to a non-uniform spectral distribution of the pumping power after a long propagation. This results in a spectrally disto ...

Large Electric-Field Induced Strain in BiFeO3 Ceramics

Dragan Damjanovic, Marija Kosec

Large bipolar strain of up to 0.36% (peak-to-peak value) was measured in BiFeO3 ceramics at low frequency (0.1 Hz) and large amplitude (140 kV/cm) of the driving field. This strain is comparable to that achievable in highly efficient morphotropic phase bou ...

AC analysis of defect cross sections using non-radiative MPA quantum model

Alexandre Schmid, Yusuf Leblebici, Davide Garetto

A multiphonon-assisted model included in a Poisson-Schroedinger solver has been applied for the calculation of the capture/emission trapping rates of Si/SiO2 interface defects and their dependence with respect to the trap energy and depth in the oxide. The ...
