Broadband high-contrast-grating-type waveplates for the terahertz range

Surya Revanth Ayyagari, Andreas K Klein, Simonas Indrišiūnas, Vytautas Janonis, Daniil Pashnev, Abdu Subahan Mohammed, Guillaume Ducournau, Andreas Stöhr, Irmantas Kašalynas

The high-contrast-grating waveplates utilizing high contrast between silicon and air refractive indexes were developed in order to perform as a quarter wave and a half wave plate in the selected THz frequency range. The waveplates possessed anti-reflective properties due to the specific inclination...

Neuromorphic Coincidence Detector for Interaural Time Difference Encoding and Sound DOA Estimation

Eugénie Dalmas, François Danneville, Michael Bocquet, Christophe Loyez

Eight decades ago, the medial superior olive (MSO) responsible for the extraction of the interaural time difference (ITD) was described as a combination of coincidence detection neurons and delay lines by Jeffress, a model largely used in spiking sound source localization systems. Coincidence...

Quantification and mitigation of the effect of resynchronization errors in ultrasound sensor network for passive imaging in elastic plates

Omar Bouchakour, Emmanuel Moulin, Lynda Chehami, Nikolay Smagin

The problem of signal desynchronization in passive imaging based on noise correlation for defect detection in elastic plates is investigated. Although a post-processing resynchronization process relying on the symmetry of noise correlation functions can be applied prior to the imaging algorithm,...

Simulation and optimization of GaAs1-xPx/Si1-yGey/Ge triple junction solar cells

A. Azzououm, A. Aissat, Jean-Pierre Vilcot

This paper focuses on studying and simulating a GaAs1-xPx/Si1-yGey/Ge triple-junction solar cell structure. First, the strain and the bandgap energy associated to the SiGe layer have been studied. The optimal germanium concentration is 0.88 with a strain around 0.45%. Then, the phosphor...
