In this conference we have brought together a community that is scientifically diverse in an event that allows for inspiring contacts about the use of COMSOL Multiphysics. It is an event to connect with the Spanish and Portuguese COMSOL Multiphysics users and participate in training ... En savoir plus
The presented analysis investigates the capacitance characteristic of a Kelvin probe regarding the geometrical transition from a movable electrode plate to a narrow tip. Moreover, predictions can be done concerning optimum geometry, sensitivity and suitable electrical measurement ... En savoir plus
Magnetoacoustic tomography with magnetic induction (MAT-MI) is a recently introduced method for imaging electrical impedance properties, which integrates classic electrical impedance tomography and ultrasonic technique. It could provide an explicitly reconstructed electrical impedance ... En savoir plus
The presence of manufacturing defects in the form of incomplete welding and missing perforated holes leads to internal leakages in mufflers. This results into unintended acoustic impedance modifications as well as the Herschel-Quincke effect. The narrow region acoustics model of COMSOL ... En savoir plus
IntroductionA new circular polarized antenna model for mobile transmission has been implemented in COMSOL Multiphysics® for needs related to shooting sports events on the move. The antenna was required to work in the UHF television frequency band (specifically, 600 MHz) and, if ... En savoir plus
An important yet rarely explored problem in room acoustics is how to correlate the decay times of modal resonances to the acoustic properties of the boundaries (walls). The room response is often described by reverberation times, but the reverberation model breaks down at low frequency, ... En savoir plus
Finite element analysis (FEA) can be used to study the electrical properties of conductive ITO thin films. Previous studies have been done on insulating thin films deposited on conductive substrates [1,2]. It was found that changes of electrode size and film thicknesses can cause huge ... En savoir plus
The measurement of dielectric constant at frequencies of 20 GHz or greater is important for specifying the optical properties of materials at millimeter wavelength. One method of measurement uses a resonant cavity containing a sample of the material, and relates the resonant frequency ... En savoir plus
COMSOL Multiphysics® has proven to be an invaluable “virtual laboratory” tool in assisting our development of a new generation of efficient analytical models describing the acoustics of highly porous fibre and foam materials. From the definition of the physical relations describing the ... En savoir plus
Nondestructive Testing (NDT) refers to a wide group of methods used in industry to evaluate the properties of a material, component or system without causing damage. These include radiography, ultrasound, electromagnetic and visual, among others. Eddy-current testing (ECT) is one such ... En savoir plus
