Variational approaches to the elasticity of deformable strings with and without mass redistribution

Stefano Giordano

Abstract: The catenary is a curve that has played a significant role in the history of mathematics, finding applications in various disciplines such as mechanics, technology, architecture, the arts, and biology. In this paper, we introduce some generalizations by applying the variational method to…

Nanorobotic Integration with Millimeter-Waves: Advancing Precise Free-Space Sensing

Nawal Alsaleh, Denis Pomorski, Mohamed Sebbache, Clément Lenoir, Kamel Haddadi

This work proposes a novel approach to advance non-contact millimeter-wave sensing capabilities through the fusion of microwave characterization techniques with nanorobotics. Firstly, we introduce a WR15 waveguide six-port radar operating around 60 GHz for precise measurement of free-space…

Loss-induced modal selection by a resistive wiremesh

Svetlana Kuznetsova, Yves Aurégan, Vincent Pagneux

This work examines the impact of local losses produced by a resistive wiremesh on the modes of an acoustic cavity. In the 1D case, we demonstrate the ability to selectively affect the modes, ranging from being completely unaffected by the wiremesh to being fully absorbed by it. This effect can be…

Microwave Imaging with Open-Ended Coaxial Probes

Kamel Haddadi, Clément Lenoir, Mohamed Sebbache, Chia-Hung Lee, Peter Burke

This work proposes an innovative approach to microwave imaging by combining robotics with open-ended coaxial probes. Traditionally, open-ended coaxial probes have been employed for precise dielectric measurements. However,their integration with robotics introduces a novel dimension,enabling dynamic…

Performance investigation of 1.5 Tb/s optical hybrid 2D-OCDMA/OFDM system using direct spectral detection based on successive weight encoding algorithm

Mohamed Rahmani, Abdelhamid Cherifi, Ghoutia Naima Sabri, Mohammed I. Al-Rayif, Iyad Dayoub, Boubakar S. Bouazza

In order to raise the performance of optical communication systems, it is imperative mainly to increase the number of available users while decreasing the bit error rate (BER) in the required spectral width. This can be challenging in optical multiplexing systems including incoherent optical code…

InAlGaN-based HEMT with very low Ohmic contact resistance regrown at 850 °C by MOVPE

Charles Pitaval, Sébastien Aroulanda, Yassine Fouzi, Nicolas Defrance, Cédric Lacam, Nicolas Michel, Nadia El Bondry, Mourad Oualli, Laurent Teisseire, Jean-Claude Jacquet, Stéphane Piotrowicz, Christophe Gaquière, Sylvain Delage

Regrown Ohmic contacts have been widely studied for high millimeter-wave applications. However, few were applied to InAl(Ga)N-based HEMT despite the lattice match benefits with GaN channel because of the poor thermal stability of the quaternary barrier. In this article, we use relatively low…
