Shining the light to terahertz spectroscopy of nL-volume biological samples

Sergey I. Mitryukovskiy, Melanie Lavancier, Flavie Braud, Goedele Roos, Theo Hannotte, Emmanuel Dubois, Jean-Francois Lampin, Romain Peretti

We present a technique allowing the confinement of a broadband terahertz pulse to a few-nL volume. The method is approved in terahertz time-domain spectroscopy study of biological samples and further perspectives are discussed.

Room-Temperature Electron Transport in Self-Assembled Sheets of PbSe Nanocrystals with a Honeycomb Nanogeometry

Maryam Alimoradi Jazi, Aditya Kulkarni, Sophia Buhbut Sinai, Joep Peters, Eva Geschiere, Michele Failla, Christophe Delerue, Arjan Houtepen, Laurens Siebbeles, Daniel Vanmaekelbergh

ABSTRACT: It has been shown recently that atomically coherent superstructures of a nanocrystal monolayer in thickness can be prepared by self-assembly of monodisperse PbSe nanocrystals, followed by oriented attachment. Superstructures with a honeycomb nanogeometry are of special interest, as theory…

Design, fabrication, and characterization of TIP-enhanced Raman spectroscopy probes based on metallic nano-antennas, Conception, fabrication et caractérisation de sondes de spectroscopie raman à exaltation de pointe à base de nano-antennes métalliques

Damien Eschimese

Since the start of the 2000s the evolution of tip-enhanced Raman spectroscopy (TERS) has enabled the simultaneous measurement of localized structural, molecular, and physicochemical properties. TERS technology combines scanning probe microscopy -- atomic force microscopy (AFM) -- with near field…, Depuis les années 2000, le développement de la spectroscopie Raman à exaltation de pointe (TERS) a permis l’accès de manière extrêmement localisée aux propriétés structurales et moléculaires à la surface de la matière et à des analyses physico-chimiques combinées. La technologie TERS associe les…

Textile split ring resonator antenna integrated by embroidery

Jianping Hao, A. Leblanc, Ludovic Burgnies, Amine-Rami Djouadi, Cédric Cochrane, François Rault, Vladan Koncar, Eric Lheurette

A split ring resonator (SRR) antenna integrated in textile by embroidery is reported. The antenna was designed and produced by targeting two goals. First, a size reduction of the antenna was achieved by means of an SRR. Secondly, the connection loss was reduced by using a copper wire dipole fixed…

Electrical conductivity enhancement of hybrid PA6,6 composite containing multiwall carbon nanotube and carbon black for shielding effectiveness application in textiles

Marzieh Javadi Toghchi, Christine Campagne, Aurélie Cayla, Pascal Bruniaux, Carmen Loghin, Irina Cristian, Ludovic Burgnies, Yan Chen

Textiles have been highly considered in applications of electromagnetic shielding effectiveness. This is mainly due to an increasing concern of health issues caused by human exposure to radiation. In the present study, the main objective was to develop a monofilament yarn made of conductive polymer…

Kalman Filter-Based Channel Estimation for Mobile-to-Mobile and Relay Networks

Ali Houssam El Husseini, Laurent Ros, Eric Pierre Simon

This paper deals with channel estimation in mobile-to-mobile communications, possibly including amplify and forward mobile relays, assuming a two-dimensional scattering environment. A second-order autoregressive (AR(2)) model with the Kalman filter is used to estimate the channel gain of the global…

Efficient Equalization for FBMC-OQAM Under Doubly Selective Channel Estimation Errors

Michel Saideh, Iyad Dayoub, Marion Berbineau

The FBMC-OQAM waveform recently has received a lot of interest due to its outstanding spectral characteristics. However, that comes with the cost of a new built-in interference introduced between its subcarriers which triggered the need for new transceiver techniques. In this letter, we propose an…
