A 6.5 - 50 GHz battery-powered compact rotary joint for polarization ellipticity measurements

A simple, efficient, and compact rotary joint has been designed, realized, and measured. It has been used intensively to perform polarization ellipticity measurements on various circularly polarized antennas (e.g., helical antennas and circularly polarized ...

Universal polarizer at 140 for DNP-enhanced NMR experiments

Stefano Alberti, Jean-Philippe Ansermet, Arnaud Comment, Emile Jacques de Rijk, Alessandro Macor

By shining mm-waves upon a sample containing unpaired electron spins, DNP provides a way to enhance NMR signals. We report the characterization of a universal polarizer for EM-waves at 140 GHz made by rectangular grooved mirrors as well as design considera ...

Ion cyclotron resonance heating with consistent finite orbit widths and anisotropic equilibria

Jonathan Graves, Wilfred Anthony Cooper, Martin Jucker

Minority ion cyclotron resonance heating is studied using the self-consistent numerical model SCENIC. This model includes 3D geometries with full shaping and anisotropic pressure effects, warm contributions to the dielectric tensor and full orbit effects. ...

High resolution displacement detection by speckle pattern analysis : accuracy limits in linear displacement speckle metrology

Hans Peter Herzig, Toralf Scharf

We propose a simple reflection measurement setup and a motion evaluation procedure based on a two dimensional recording of subsequent speckle images. The averaging of cross correlation functions is used to measure displacements. We demonstrate experimental ...

Combinatorial Discovery and Optimization of Amorphous HfO2-Nb2O5 Mixture with Improved Transparency

Paul Muralt, Patrik Willi Hoffmann, Silviu Cosmin Sandu, Ali Dabirian, Yury Kuzminykh, Estelle Wagner, Scott Harada, Bamdad Afra, Giacomo Benvenuti

Combinatorial high vacuum chemical vapor deposition (HV-CVD) of mixed HfO2-Nb2O5 thin films has been demonstrated to yield amorphous layers at substrate temperatures where individually deposited pure HfO2 and Nb2O5 films are polycrystalline. Spectroscopic ...

Determination of local optical properties of the rat barrel cortex during neural activation: Monte-Carlo approach to light propagation

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Stéphane Chamot, Elena Migacheva

Spatially-spectrally-resolved reflectance measurements allow in vivo measuring the optical coefficients of absorption and scattering within the cortical tissue. This method, if applied to neural tissue during enhanced activity, could allow a straightforwar ...

All-optical switching in an optofluidic polydimethylsiloxane: Liquid crystal grating defined by cast-molding

Demetri Psaltis, Andreas Vasdekis, Julien Cuennet, Luciano De Sio

We report an optofluidic photoswitchable grating, based on a polydimethylsiloxane periodic structure on a glass substrate, separated by a thin liquid crystal film. The polydimethylsiloxane microstructure was realized via high resolution replica molding and ...

Retardation-induced plasmonic blinking in coupled nanoparticles

Olivier Martin, Holger Fischer

We study how retardation leads to interference effects in radiatively coupled plasmonic nanoparticles. We show that inclined illumination through a glass substrate on two plasmonic particles results in either an enhanced field or an attenuated field locali ...
