Program
11:00 - 13:00 Introduction to EM Modelling with COMSOL Multiphysics
14:00 - 16:00 Hands-on Workshop
Contents
Electrical engineering is one of the technological cornerstones of modern society. Electricity is used to distribute power and information with a minimum of losses and delay. Imagine what life would be without it. This hands-on workshop contains examples that illustrate the modeling of electromagnetic devices in the AC/DC and RF Modules for COMSOL Multiphysics.
The exercises of this hands-on session include:
Eddy-current distribution and dissipated power in a plate, depending on the plates conductivity and permeability.
· Parallel-plate capacitor used in MEMS applications. Electrostatic analysis, extract the lumped capacitance of a device.
· Circular motion of a rotor with permanent magnets generates an induced EMF in a stator winding.
· A submarines magnetic signature, that is, the local disturbance in the earth's magnetic field that the sub causes.
· Transition between a rectangular and an elliptical waveguide. Calculate the scattering S-parameters that measure the transmission and reflection of the wave.
· Conical antenna where axial symmetry reduces the problem size. S-parameter analysis, frequency sweep, and far-field calculations.
· A nonreciprocal microwave component. A small cylinder of a gyrotropic material in a three-port waveguide junction causes it to act as a matched coupler for waves propagating in one direction and an isolator for waves propagating in the other direction.
· Thermal drift in a microwave filter. This multiphysics model uses three application modes: shell expansion, moving mesh, and electromagnetic waves.
