Experimental investigation of the lateral resolution of a homemade near field microwave microscope

Tianjun Lin, S. Gu, T. Lasri

In this paper an experimental investigation of the lateral resolution of a homemade near field microwave microscope (NFMM) is reported. The optimal lateral resolution is studied by a thorough analysis of the influence of critical parameters such as the stand-off distance, the tip apex size and the...

Luminescence imaging of photoelectron spin precession during drift in a p-type GaAs microfabricated Hall bar

V. Notot, D. Paget, A. Rowe, L. Martinelli, Fabian Cadiz, S. Arscott

Using a microfabricated p-type GaAs Hall bar, it is shown that the combined application of co-planar electric and magnetic fields enables the observation of spatial oscillations of the photoluminescence circular polarization due to the precession of drifting spin-polarized photoelectrons....

New adaptive filters as perceptual preprocessing for rate-quality performance optimization of video coding

Eloïse Vidal, Nicolas Sturmel, Christine Guillemot, Patrick Corlay, François-Xavier Coudoux

In this paper, we introduce two perceptual filters as pre-processing techniques to reduce the bitrate of compressed high-definition (HD) video sequences at constant visual quality. The goal of these perceptual filters is to remove spurious noise and insignificant details from the original video...
