Surface acoustic phonons and surface roughness have an important effect on the carrier mobility, especially in the thin inversion layer under the gate in MOSFETs. The Lombardi surface mobility model adds surface scattering resulting from these effects to an existing mobility model using ... En savoir plus
This example resembles the well-known double-slit interference experiment often demonstrated in schools with water waves or sound. The model mimics the plane-wave excitation with two thin waveguides leading to slits in a screen and computes the diffraction pattern on the opposite side of ... En savoir plus
This tutorial demonstrates how to compute the response of an ultrasonic car parking sensor transducer coupling Pressure Acoustics, Frequency Domain, Solid Mechanics, and Piezoelectric Materials. The far-field radiation pattern of the transducer is then used as a source for a Ray ... En savoir plus
During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... En savoir plus
One-sided magnets are magnets designed to have both magnetic poles emerging from the same side of the magnet. This results in the magnetic flux being concentrated on one side of the magnet. These kinds of magnets are found in many applications from the common fridge magnet to particle ... En savoir plus
This collection of examples demonstrates how to use the COMSOL® API with the Java® programming language, as described in the Application Programming Guide under Programming Examples. Please note that these examples are simplified for clarity and do not include error handling or ... En savoir plus
This tutorial model analysis of a microstrip patch antenna shows how to couple the finite element method (FEM) to the boundary element method (BEM) for evaluating the field outside the FEM computational domain. The model computes the S-parameter, near-field distribution, and far-field ... En savoir plus
In this example, a settlement and heave analysis of a shallow foundation resting on an unsaturated soil stratum is conducted with the Modified Cam-Clay and Extended Barcelona Basic soil models. The effect of pore suction due to movements in the phreatic line and the resulting settlement ... En savoir plus
Several different approaches to optimizing a ten-turn axisymmetric coil are presented. First, the current in each turn is adjusted with the objective of having a uniform magnetic flux density along the centerline. Second, the currents are adjusted to minimize power dissipation with a ... En savoir plus
The dynamic response of a human body in any vibration environment can be predicted using this biomechanical model. In the automobile industry for instance, this model can be used in ride quality simulation and designing vibration isolators such as seats. In this example, a ... En savoir plus
