DESCRIPTION:The numerical simulation of the Helmholtz and Maxw
ell equations play \;a critical role in chip a
nd antennadesign\, radar cross section determinati
on\, speaker design\, \;biomedical imaging\, w
ireless communications\, and the development of ne
w meta-materials and better waveguides to name a f
ew. In order to enable design by simulation for pr
oblems arising \;in these applications\, \
;automatically adaptive solvers which resolve the
complexity of the geometry \;and the input dat
a play a critical role. \;In two dimensions\,
this has been made possible through the developmen
t of high-order integral equation based solvers wh
ich rely on well-conditioned integral representati
ons\, efficient quadrature formulas\, and coupling
to fast multipole methods/fast direct solvers.&nb
sp\;However\, much is still to desired of these so
lvers \;in three dimensions (both in terms of
their efficiency and accuracy)\, \;particularl
y in the context of enabling automatic adaptivity&
nbsp\;in complex geometries. In this talk\, I will
present efficient high-order accurate solvers for
solving \;boundary integral equations in comp
lex three dimensional geometries with focus on the
following two issues --- quadrature methods for c
omputing singular integrals on high order meshes s
urfaces\, and a locally corrected quadrature frame
work for fast multipole accelerated iterative solv
ers and strong skeletonization based direct solver
s.
