The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. ... Per saperne di più
For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and ... Per saperne di più
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 ... Per saperne di più
The waveguide device modeled here specifically demonstrates the exploration of a small, but very important, subset of components of the family of microwave hardware devices designed to facilitate the optimized transfer of power from the generating source to the consuming load. Each of ... Per saperne di più
In this contribution we present the results of the numerical modeling and performance optimization study of a diaphragm pump for drug infusion. The main objective is to develop a numerical model that replicates the pumping cycle (400ms) and also provides indications about the variation ... Per saperne di più
The study of plasmonic structures continues to be at the forefront of research in nanotechnology and condensed matter physics. Here, we present a numerical model we have created and verified to characterize the frequency dependence of the effective magnetic permeability and permittivity ... Per saperne di più

This paper analyzes different types of coil systems to produce volumes of uniform magnetic field. Some types of coil system are presented in this paper such as Helmholtz, Merritt, and Ruben coil systems. In the study coil systems are intended to produce a magnetic flux density of 2µT in ...

3D-modeling of magnetic components with FEM is challenging due to the involved nonlinearities and coupling effects between different physical domains. A specific issue is the consideration of lamination due to the high resulting element count for thin layers. Therefore, several ... Per saperne di più
This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence ... Per saperne di più
