Inverse medium scattering for a nonlinear Helmholtz equation
Roland Griesmaier, Marvin Knöller, Rainer Mandel
We discuss a time-harmonic inverse scattering problem for a nonlinear Helmholtz equation with compactly supported inhomogeneous scattering objects that are described by a nonlinear…
An asymptotic representation formula for scattering by thin tubular structures and an application in inverse scattering
Yves Capdeboscq, Roland Griesmaier, Marvin Knöller
We consider the scattering of time-harmonic electromagnetic waves by a penetrable thin tubular scattering object in three-dimensional free space. We establish an asymptotic represe…
Monotonicity in inverse medium scattering on unbounded domains
Roland Griesmaier, Bastian Harrach
We discuss a time-harmonic inverse scattering problem for the Helmholtz equation with compactly supported penetrable and possibly inhomogeneous scattering objects in an unbounded h…
A note on analyticity properties of far field patterns
Roland Griesmaier, Nuutti Hyvönen, Otto Seiskari
In scattering theory the far field pattern describes the directional dependence of a time-harmonic wave scattered by an obstacle or inhomogeneous medium, when observed sufficiently…
