Frictional contact of two spheres for arbitrary 2D loading

Vladislav Aleshin, Koen van den Abeele

Frictional interaction of two elastic spheres is a fundamental problem of contact mechanics. The tangential displacement depends on the normal and tangential force in a complicated and, in general, hysteretic way. We analyze in detail the key memory characteristic of the system (the traction...

Organosilicon polymers deposition by PECVD and RPECVD on micropatterned substrates

Philippe Supiot, Céline Vivien, Karine Blary, V. Rouessac

Thin films of organosilicon materials produced by plasma-assisted deposition are frequently used because of their multifunctional character, but few comparative studies into their growth on structured surfaces are available. Two types of CVD processes, plasma-enhanced (PE)CVD and remote plasma-...

Time reversed acoustics techniques for elastic imaging in reverberant and nonreverberant media : an experimental study of the chaotic cavity transducer concept

B. van Damme, K. van den Abeele, Y.F. Li, Olivier Bou Matar

In view of emerging imaging technologies based on the combination of Time Reversed Acoustics (TRA) with Nonlinear Elastic Wave Spectroscopy (NEWS) for the detection and localization of micro-damage in solids, we have investigated the benefits of chirped source signal excitation, inverse filtering...

Milliwatt-level output power in the sub-terahertz range generated by photomixing in a GaAs photoconductor

Emilien Peytavit, Sylvie Lepilliet, Francis Hindle, Christophe Coinon, Tahsin Akalin, Guillaume Ducournau, Gaël Mouret, Jean-Francois Lampin

It is shown from accurate on-wafer measurement that continuous wave output powers of 1.2 mW at 50 GHz and 0.35 mW at 305 GHz can be generated by photomixing in a low temperature grown GaAs photoconductor using a metallic mirror Fabry-Pérot cavity. The output power is improved by a factor of about...
