ELEC 0041: Modeling and design of electromagnetic systems - Spring 2017


Tue 07/02Introduction to computational electromagnetics. Maxwell equations, fields and related global quantities (charge, voltage, current, magnetic flux), material relations, boundary conditions, interface conditions. Electrostatic, electrokinetic, magnetostatic, magnetodynamic and full wave models. Introduction to Gmsh (building of geometries and meshes at progressive levels of complexity) and GetDP (elementary notions). First practical example on electrostatics using the electric scalar potential. (Slides, part 1)
Tue 14/02Introduction to finite element formulations (least square interpolation, electrostatic and electrokinetic models, 1D and 2D cases). Tonti diagrams. Introduction to GetDP in parallel with theoretical tools related to the finite element method: 1D and 2D finite elements (degree 1 and 2), reference and real finite elements, change of coordinates, interpolation of scalar fields (degrees of freedom, basis functions), least square interpolation formulation, integral formulation. (Slides, part 2)
