This tutorial utilizes the Particle Beam feature to examine the performance of a high-precision spectrometer. An ion beam is subjected to electric and magnetic forces, and only a fraction of the incoming beam is transmitted to the detector. The Particle Counter feature is used to compute ... En savoir plus
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and when the rotor is at a ... En savoir plus
This model is used to demonstrate the solution to a classic brainteaser in electromagnetics. A long loop of wire is connected to a source and a receiver, which are placed 1 meter apart. The objective of the model is to compute how long it takes for the receiver to sense when the source ... En savoir plus
Gas cells have several applications in the design of scientific instruments. A gas cell is used to define a high-pressure region within the instrument's main vacuum system. For example, in this application, note we are designing a high-pressure region 100 mm long, with an operating ... En savoir plus
This model treats the free convection of argon gas within a light bulb. It shows the coupling of heat transport (conduction, radiation and convection) to momentum transport (non-isothermal flow) induced by density variations caused by temperature. COMSOL Multiphysics model makes it ... En savoir plus
A Mach-Zehnder modulator is used for controlling the amplitude of an optical wave. The input waveguide is split up into two waveguide interferometer arms. If a voltage is applied across one of the arms, a phase shift is induced for the wave passing through that arm. When the two arms are ... En savoir plus
This application demonstrates how the Application Builder in the COMSOL Multiphysics® software can be used to make advanced cable modeling available to a general audience. At its core is a multiphysics model based on the technology introduced in the Cable Tutorial Series. The ... En savoir plus
This models pressure-dependent heating of 4 inch wafer on unipolar electrostatic chuck. Wafer sits on top of ring with electrostatic force holdong down wafer to counter upward pressure from gas flowing in gap between wafer and chuck surface. It is a problem involving 4 coupled physics ... En savoir plus
When high-fidelity measurement microphones are calibrated, a pressure reciprocity calibration method is used. During calibration, two microphones are connected at each end of a closed cylindrical cavity. For the calibration procedure, it is important to understand the acoustic field ... En savoir plus
The suspension of a loudspeaker is designed to keep the membrane in place and avoid any rocking movement of the voice coil. At low frequencies, where the displacement of the membrane is significant, the stiffness of the suspension varies along the movement of the voice coil. This ... En savoir plus
