Carbon Nanotubes-Based Air-Filled Waveguide for D-Band Applications

Amit Kumar, Ankit Kumar Verma, Rong Tao Jiang, Jian Ping Zou, Chong Wei Tan, Dominique Baillargeat, Stephane Bila, Philippe Coquet, Beng Kang Tay

This letter presents the design, fabrication, and characterization of a novel D-band (110–170 GHz) air-filled waveguide (AFWG) with vertically aligned carbon nanotube (VACNT) sidewalls. The waveguide was designed using full-wave 3-D electromagnetic simulations combined with an equivalent VACNT bulk...

Ondes Élastiques Topologiquement Guidées pour l’Haptique de Surface

Massaï Hatoumva, Charles Croënne, Bertrand Dubus, Arthur Paté, Marco Miniaci, Florian Allein, Frédéric Giraud

Les cristaux phononiques topologiques marquent une avancée majeure dans le contrôle des ondes élastiques en permettant la synthèse de modes localisés spécifiques (états de bords). Si les propriétés de ces modes font actuellement l’objet de nombreuses études, la question de leur perception haptique...

Configurational forces in the field of defective processes: a unifying approah

Stefano Giordano, Salvatore Di Stefano, Claudia Binetti, Giuseppe Puglisi

In this contribution, we develop a theoretical framework for the study of defect propagation in solid media, proposing a unified approach to the evolution of both topological and material defects. In the context of the Continuum Mechanics, the term defect refers to the change in either the material...
