Inverse spectral problems on a closed manifold
Katsiaryna Krupchyk, Yaroslav Kurylev, Matti Lassas
In this paper we consider two inverse problems on a closed connected Riemannian manifold . The first one is a direct analog of the Gel'fand inverse boundary spectral problem…
Effectiveness and improvement of cylindrical cloaking with the SHS lining
Allan Greenleaf, Yaroslav Kurylev, Matti Lassas +1
We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as t…
Electromagnetic wormholes via handlebody constructions
Allan Greenleaf, Yaroslav Kurylev, Matti Lassas +1
Cloaking devices are prescriptions of electrostatic, optical or electromagnetic parameter fields (conductivity , index of refraction , or electric permittivity a…
Electromagnetic wormholes and virtual magnetic monopoles
Allan Greenleaf, Yaroslav Kurylev, Matti Lassas +1
We describe new configurations of electromagnetic (EM) material parameters, the electric permittivity and magnetic permeability , that allow one to construct from metamateri…
Inverse boundary spectral problem for Riemannian polyhedra
Anna Kirpichnikova, Yaroslav Kurylev
We consider an admissible Riemannian polyhedron with piece-wise smooth boundary. The associated Laplace defines the boundary spectral data as the set of eigenvalues and restriction…
Time reversal methods in unknown medium and inverse problems
Kenrick Bingham, Yaroslav Kurylev, Matti Lassas +1
A novel method to solve inverse problems for the wave equation is introduced. The method is a combination of the boundary control method and an iterative time reversal scheme, lead…
