Plasmonic Properties of Bimetal Nanoshell Cylinders and Spheres
Plasmonics is a new branch of the fascinating field of photonics and develops concepts to quench light beyond the diffraction limit and enhance electromagnetic fields. These enhancements occur in metals as localized surface plasmon polaritons (LSP) a coupling of the surface density ... Per saperne di più
Enhanced Surface Plasmon Polariton Propagation Induced by Active Dielectrics
We present numerical simulations for the propagation of surface plasmon polaritons in a dielectric-metal-dielectric waveguide using COMSOL Multiphysics® software. We show that the use of an active dielectric with gain that compensates metal absorption losses enhances substantially ... Per saperne di più
Virtual Prototype of a Dielectric Window for High-Power Microwave Tubes
This paper describes the Virtual Prototype of a Dielectric Window or High Power Microwave Vacuum Tubes and Linear Accelerators. Design formulas are provided and Computer Aided Design techniques based on COMSOL Multiphysics® software are proposed. The virtual prototype considers the ... Per saperne di più
Plasmonics of Nano-Gaps
Plasmons, i.e. the collective oscillations of electrons in a metallic nano-structure, lead to strong light scattering, absorption and an enhancement of the local electromagnetic field. In this work, the local electric-field enhancement in a system of dielectric nanoparticles placed ... Per saperne di più
Biological Effects of Microwave Radiation
Microwave technology has provided with many exciting new therapeutic and diagnostic methods.

Improving Heating Uniformity of Dried Fruit in RF Treatments for Pest Control: Model Development and Validation
Non-uniform heating is one of the most important challenges during the development of radio frequency (RF) heat treatments for pest control. A computer simulation model using finite element–based COMSOL Multiphysics® software was developed to investigate the heating uniformity of raisins ... Per saperne di più
CFD/Electromagnetics Interactions via Realistic Heat and Mass Transfer to Moist Substrates
Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase ... Per saperne di più
