Recovering the conductivity at the boundary from the Dirichlet to Neumann map: a pointwise result
A formula is given for recovering the boundary values of the coeÆcient of an elliptic operator, div r, from the Dirichlet to Neumann map. The main point is that one may recover without any a priori smoothness assumptions. The formula allows one to recover the value of pointwise. Let R; n 2, be a bounded open set with Lipschitz boundary and let : ! R satisfy 1 (x) for some > 0. Let L = div r be...
متن کاملThe generalised Dirichlet to Neumann map for moving initial-boundary value problems
We present an algorithm for characterising the generalised Dirichlet to Neumann map for moving initial-boundary value problems. This algorithm is derived by combining the so-called global relation, which couples the initial and boundary values of the problem, with a new method for inverting certain one-dimensional integrals. This new method is based on the spectral analysis of an associated ODE...
متن کاملFaster convergence and higher accuracy for the Dirichlet-Neumann map
New techniques allow for more efficient boundary integral algorithms to compute the Dirichlet–Neumann map for Laplace’s equation in two-dimensional exterior domains. Novelties include a new post-processor which reduces the need for discretization points with 50 per cent, a new integral equation which reduces the error for resolved geometries with a factor equal to the system size, systematic us...
متن کاملUniqueness by Dirichlet-to-neumann Map on an Arbitrary Part of Boundary in Two Dimensions
We prove for a two dimensional bounded simply connected domain that the Cauchy data for the Schrödinger equation measured on an arbitrary open subset of the boundary determines uniquely the potential. This implies, for the conductivity equation, that if we measure the current fluxes at the boundary on an arbitrary open subset of the boundary produced by voltage potentials supported in the same ...
متن کاملDirichlet-to-Neumann Map Method with Boundary Cells for Photonic Crystals Devices
In a two-dimensional (2D) photonic crystal (PhC) composed of circular cylinders (dielectric rods or air holes) on a square or triangular lattice, various PhC devices can be created by removing or modifying some cylinders. Most existing numerical methods for PhC devices give rise to large sparse or smaller but dense linear systems, all of which are expensive to solve if the device is large. In a...
