MICDE Seminar: B. Shanker, Michigan State University, on “Electromagnetics on subdivision surfaces” — April 8
April 8, 2015 @ 12:00 am
Computation of electromagnetic scattering from complex objects is typically accomplished as follows: (i) obtain a discrete representation of the geometry using standard meshing tools, (ii) define a basis set on the discrete geometry, and (iii) solve the resulting system of equations. Meshes used in the analysis are typically piecewise flat or locally higher order and continuous only interior to patches. This stands in stark contrast to powerful surface descriptions developed in the computer graphics community which entail higher order geometry processing that results in surfaces that are C2 everywhere or almost everywhere. In this talk, we will explore the exploitation of these features with the context of electromagnetic solver. Specifically, we will explore the use of subdivision surfaces within (a) isogeometric framework, (ii) classical higher order RWG basis functions, and (iii) generalized method of moments framework.
