In this paper will be presented how an electronic system and its components will respond in case of an impact of an external electromagnetic pulse (EMP). In the first instance the coupling process of transient electromagnetic pulses into electronic systems will be shown. Out of that the ... Per saperne di più
Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying ... Per saperne di più
In this paper resonances in tapered double-port TEM waveguides are used as benchmark for simulations. FEM simulations with COMSOL Multiphysics® and simulations using generalised telegraphist's equations with MATLAB® are compared to ananalytical method capable of calculating the ... Per saperne di più
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
Recent studies have been devoted to develop mathematical models to simulate the food processing using the porous media approach. The aim of this study is to simulate the microwave drying of osmodehydrated food by means of modeling the mass, energy and momentum transfer using the porous ... Per saperne di più
Devices of mobile communication require smallest sizes of antennas. This is one of the applications of fractal antennas which have reduced size or are multiband and can be used for mobile phone, RFID, Wi-Fi, digital TV, among other applications. The Koch fractal geometry allows better ... Per saperne di più
The Marine Controlled Source ElectroMagnetic (marine CSEM) is a geophysical method used by the oil industry to investigate resistive targets in the sediments under the ocean floor. In this work we simulate marine CSEM data including 1D, 2.5D and 3D modeling. The results obtained with ... Per saperne di più
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
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
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
