After 11 years and several releases, the application usage has grown along with number of licenses we are responsible for. This paper will broaden ... En savoir plus

Antenna and Plasmonic Properties of Scanning Probe Tips at Optical and Terahertz Regimes

A. Haidary[1], P. Grütter[1], Y. Miyahara[1]
[1]Physics Department, McGill University, Montreal, QC, Canada

A wide variety of near-field optical phenomena such as apertureless near-field scanning microscopy (ANSM) at optical and terahertz (THz) regimes and surface enhanced Raman scattering relies on the electric field enhancement at the end of a sharp tip. Achieving and controlling this ... En savoir plus

Multiphysics Modeling of Swelling Gels

A. Lucantonio[1], P. Nardinocchi[1], L. Teresi[2]
[1]Università degli Studi La Sapienza, Roma, Italy
[2]LaMS - Modelling & Simulation Lab, Università degli Studi Roma Tre, Roma, Italy

Polymer gels belong to the realm of soft active materials as they are capable of responding to a non-mechanical stimulus – the permeation of a solvent – with a mechanical action – a volume change, thanks to the coupling between different physics. This mechanism of coupling can be ... En savoir plus

Drag Fluctuations of a Fully Deployed Flow Actuator Embedded Inside Turbulent Boundary Layer Flow

Dr. A. Elzawawy[1]
