High-Directivity Terahertz Silicon-Lens TEM Horn Antenna

Kevin Froberger, Guillaume Ducournau, Jean-Francois Lampin

Abstract: We present a new design of TEM horn antenna (TEM-HA), which is a combination of a silicon lens and a standard TEM-HA, for the emission of terahertz radiations up to several hundreds of GHz. This paper presents the design and the simulation of such an antenna associated with an anti-…

Retrieving material and metamaterial parameters directly from time-domain spectroscopy time trace

Romain Peretti, Sergey I. Mitryukovskiy, Kevin Froberger, Jean-Francois Lampin

Abstract: We present the Fit@TDS software that enables the retrieving of the refractive index from a time-domain spectroscopy experiment. The software does not only use common methods of frequency-domain refractive index retrieving but also include a time-domain optimization algorithm that enables…

Experimental Demonstration Of 20dB Nonreciprocity Around 1.5THz On A InSb Magnetoplasmonic Grating Mirror At 77K

O. Stepanenko, T. Horak, S. Mitryukovskiy, Romain Peretti, Jean-Francois Lampin, Mathias Vanwolleghem, J. Chochol, K. Postava

Abstract: We demonstrate experimental results on a novel compact terahertz isolator based on a nonreciprocal InSb magnetoplasmonic mirror. Isolating efficiency is compared at 300K and 77K, achieving 20dB at QCL compatible temperatures.

High temperature piezoelectric glass-ceramics for SAW sensors

Maurice Gonon, F. Dupla, Marie-Sophie Renoirt, Nikolay Smagin, Marc Duquennoy, Gregory Martic

During the last ten years, interest in sensors based on surface acoustic waves (SAW) has been growing. Basically, these devices use two set of interdigitate electrodes on a piezoelectric substrate to generate, propagate and receive an acoustic signal (Figure 1). Changes in propagation conditions,…

Performance evaluation of silicon based thermoelectric generators interest of coupling low thermal conductivity thin films and a planar architecture

Thierno-Moussa Bah, Stanjen Didenko, Stephane Monfray, Thomas Skotnicki, Emmanuel Dubois, J.F. Robillard

This study aims to compare a silicon ThermoElectric Generator design (TEG) with a commercial TEG made of BiTe alloy commercialized till recently by Micropelt. The objective is to show that recent advances in heat conduction modulation by silicon planar nanostructures may potentially improve…

Frequency locking and controllable chaos through exceptional points in optomechanics

P. Djorwe, Yan Pennec, Bahram Djafari-Rouhani

We engineer mechanical gain (loss) in a system formed by two optomechanical cavities (OMCs), that are mechanically coupled. The gain (loss) is controlled by driving the resonator with laser that is blue (red) detuned. We predict analytically the existence of multiple exceptional points (EPs), a…

[Invited] Transmission Energy Analysis And Modeling Of A Video Sensor Node In The Context Of Next Generation WVSN

Achraf Ait-Beni-Ifit, Othmane Alaoui-Fdili, Patrick Corlay, François-Xavier Coudoux, Mohammed El Hassouni

Energy consumption is of main concern in the field of Next generation Wireless Video Sensor Networks (WVSN) where energy resources are limited, consisting only in the battery of sensor nodes that determines the node's lifetime. In the current work, Intra-Only H.265/HEVC is considered as video…
