We present a procedure to obtain reliable EM responses for a SIW interconnect with microstrip line transitions. The procedure focuses on two COMSOL® configuration settings: meshing size and simulation bounding box. Once both are properly configured, the implemented structure is tested by ... En savoir plus
Multiphysics simulations play an important role in researchanddevelopment in almost all disciplines. Therefore it is necessary to teach them at the universities to provide the industry with well-trained graduate students. In our lectures about the finite element method we use a simple ...

We present an optimization procedure to improve the propagation properties of the depressed-cladding, buried micro-structured waveguides formed in a z-cut lithium niobate (LN) crystal by high repetition rate femtosecond (fs) laser writing. It is shown that the propagation wavelength ... En savoir plus
Borehole heat exchangers (BHE) in connection with heat pumps and floor heating in many countries are becoming an alternative to conventional heating or cooling systems using fossil resources. We describe how 1D components for heat transport in pipes can be coupled with a 2D or 3D ... En savoir plus
A COMSOL Multiphysics® model is developed for ideal type II superconductor with Ginzburg-Landau (GL) parameter κ~50 typical for practical high field, high current superconductors The model is validated by computing magnetization of such superconductor for every value of external magnetic ...

Novel class of artificial optical antennas are of great interest in biosensing applications of nanoplasmonics due to their unique and tunable spectral properties. Silver colloid spheres covered with L-cysteine were studied experimentally by spectroscopy and TEM and numerically by a ... En savoir plus
The transfer of sucrose and fructooligosaccharides to melon and water to solution was modeled based on generalized form of Fick’s second law for simultaneous diffusion and resolved by the finite element method using the software package COMSOL Multiphysics® software. The diffusion ... En savoir plus
Analysis of concrete structures is usually carried out by destructive methods. The internal volume flaws directly influence concrete properties. Such inclusions are empty or even resulting from the manufacturing process or degradation by percolation leaching dissolution and chemical ... En savoir plus
As embalagens de produtos alimentícios são hoje em dia predominantemente feitas com cartão tipo LPB (Liquid Packaging Board) e usualmente estocadas de forma empilhada, tanto nas prateleiras como nos depósitos dos supermercados. O LPB é um compósito multicamadas de construção complexa, ... En savoir plus
Levitation has found important applications in several areas of engineering, from microgravity to transportation systems. Electrodynamic levitation consists of the interaction of a varying in time magnetic field – provided by an alternating voltage supplying a coil or a moving permanent ... En savoir plus
