In the context of non-destructive evaluation methods, eddy-current testing plays a prominent role in crack-detection problems, due to its various attractive features. One of the physical quantities that typically interest us in such type of problems is the – complex – coil impedance and ... Per saperne di più
One of the advantages of microwave heating of a dielectric material is the direct transfer of electromagnetic energy to the core of the dielectric through interactions between electromagnetic waves and the dielectric, without heating the surrounding elements [1]. For an industrial ... Per saperne di più
Ultrasound Imaging probes are specific devices that require a very detailed design of acoustic impedance match for the stack of layers that form the probe head (1,3). These are typically made of silicone rubber, special epoxy resins, polyurethanes and, of course, piezoelectric ... Per saperne di più
The main purpose of a drive unit is to transform the electrical signal at its terminals into acoustic waves via two transduction mechanisms: electro-mechanical and mechano-acoustical. In this paper only the electro-mechanical transformation is discussed in view of a future optimization ... Per saperne di più
Neuromodulation, a closed-loop therapy that combines the recording and stimulation of neurons using implanted electrodes, is widely considered the future of care for many neurological diseases including epilepsy and Parkinson’s. Existing neuromodulation therapies, however, are limited by ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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, ... Per saperne di più
