We investigate fixed energy scattering from conical potentials having an irregular cross-section. The incident wave can be any arbitrary non-trivial Herglotz wave. We show that a large number of such local conical scatterers scatter all incident waves, meaning that the far-field will always be non-zero. In essence there are no incident waves for which these potentials would seem transparent at any given energy. We show more specifically that there is a large collection of star-shaped cones…

Scattering by Curvatures, Radiationless Sources, Transmission Eigenfunctions, and Inverse Scattering Problems
TLDR
It is shown that a scatterer cannot be completely invisible if its support is sufficiently small (compared to the underlying wavelength and scattering intensity), and new intrinsic geometric properties of interior transmission eigenfunctions near high-curvature points are derived.
Acoustic Scattering from Corners, Edges and Circular Cones
Consider the time-harmonic acoustic scattering from a bounded penetrable obstacle imbedded in an isotropic homogeneous medium. The obstacle is supposed to possess a circular conic point or an edge
Shape Identification in Inverse Medium Scattering Problems with a Single Far-Field Pattern
TLDR
It is shown that the smoothness conditions in previous corner scattering results are only required near the corners, and it is proved that its shape and location can be uniquely determined by the far-field pattern incited by a single incident wave at a fixed frequency.
Free boundary methods and non-scattering phenomena
TLDR
It is shown that every penetrable obstacle with real-analytic boundary admits such an incident wave that does not scatter, and that there is a dichotomy for boundary points of any penetrables obstacle having this property.
On corner scattering for operators of divergence form and applications to inverse scattering
Abstract We consider the scattering problem governed by the Helmholtz equation with inhomogeneity in both “conductivity” in the divergence form and “potential” in the lower order term. The support of
Corners and edges always scatter
Consider time-harmonic acoustic scattering problems governed by the Helmholtz equation in two and three dimensions. We prove that bounded penetrable obstacles with corners or edges scatter every
Nonradiating Sources and Transmission Eigenfunctions Vanish at Corners and Edges
TLDR
It is shown that nonradiating sources having a convex or non-convex corner or edge on their boundary must vanish there, and the same holds true for smooth enough transmission eigenfunctions.
Introduction to complex orbital momenta
SummaryIn this paper the orbital momentumj, until now considered as an integer discrete parameter in the radial Schrödinger wave equations, is allowed to take complex values. The purpose of such an
Corners Always Scatter
We study time harmonic scattering for the Helmholtz equation in $${\mathbb{R}^n}$$Rn. We show that certain penetrable scatterers with rectangular corners scatter every incident wave nontrivially.
