[3] Department of Physics, EMAT Research Group, University of Antwerp, Antwerp, Belgium

Silver nanoparticles are valuable in the field of plasmonics since silver has a higher field enhancement factor compared to other metals that possess plasmonic properties. The plasmonic properties of silver nanoparticles can be finely tuned to the incident light wavelength through their ... En savoir plus

Using COMSOL to Solve for Currents along a Thin-Wire Antenna Excited by a Lumped Source

A. Shoory, A. Smorgonskiy, and F. Vega
Electromagnetic Compatibility (EMC) group, Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland

In this paper, we will present simulation results obtained using COMSOL RF module for the current along a wire antenna in both frequency and time domains. The structure is excited through a lumped (voltage or current) source at its center. For the frequency domain simulations we compare ... En savoir plus
