Chebyshev collocation Dirichlet-to-Neumann map method for diffraction gratings.
For diffraction gratings with layered refractive index profiles, the Fourier modal method is widely used. However, it is quite expensive to calculate the eigenmodes for each layer, especially when the structure involves absorptive media. We develop an efficient method that avoids the eigenvalue problems based on the so-called Dirichlet-to-Neumann (DtN) map. For each layer, the DtN map is an ope...
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 کاملAsymptotic Approximation of the Dirichlet to Neumann Map of High Contrast Conductive Media
We present an asymptotic study of the Dirichlet to Neumann map of high contrast composite media with perfectly conducting inclusions that are close to touching. The result is an explicit characterization of the map in the asymptotic limit of the distance between the particles tending to zero.
متن کاملOn a Characterization of the Kernel of the Dirichlet-to-neumann Map for a Planar Region
We will show that the Dirichlet-to-Neumann map Λ for the electrical conductivity equation on a simply connected plane region has an alternating property, which may be considered as a generalized maximum principle. Using this property, we will prove that the kernel, K, of Λ satisfies a set of inequalities of the form (−1) n(n+1) 2 detK(xi, yj) > 0. We will show that these inequalities imply Hopf...
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 ...
