Frequency-Explicit Shape Holomorphy in Uncertainty Quantification for Acoustic Scattering
Ralf Hiptmair, Christoph Schwab, Euan A. Spence
We consider frequency-domain acoustic scattering at a homogeneous star-shaped penetrable obstacle, whose shape is uncertain and modelled via a radial spectral parameterization with…

Coupled Boundary and Volume Integral Equations for Electromagnetic Scattering
Ignacio Labarca-Figueroa, Ralf Hiptmair
We study frequency domain electromagnetic scattering at a bounded, penetrable, and inhomogeneous obstacle . From the Stratton-Chu integral representation,…
