From Analytical to Numerical Methods and Back: Trefftz Schemes, Whitney Forms, and Optical Magnets

Prof. Dr. Igor Tsukerman, University of Akron, USA

16 Jun 2011, 17:00; Location: S4|10-1

Several examples of a curious interplay between analytical and numerical methods will be presented. First, accurate local (semi-)analytical Trefftz approximations lead to high-order difference schemes and to singularity-free boundary-difference methods. Second, Whitney-like interpolation, well established in finite element analysis, is now put to a new use in a rigorous homogenization theory of metamaterials. This explains, in particular, “optical magnets” – artificial magnetism at high frequencies.
