Sound absorption by perforated walls along boundaries
Patrizia Donato, Agnes Lamacz, Ben Schweizer
We analyze the Helmholtz equation in a complex domain. A sound absorbing structure at a part of the boundary is modelled by a periodic geometry with periodicity . A…
Representation of solutions to wave equations with profile functions
Agnes Lamacz, Ben Schweizer
Solutions to the wave equation with constant coefficients in can be represented explicitly in Fourier space. We investigate a reconstruction formula, which provides…
Mathematical analysis of transmission properties of electromagnetic meta-materials
Mario Ohlberger, Ben Schweizer, Maik Urban +1
We study time-harmonic Maxwell's equations in meta-materials that use either perfect conductors or high-contrast materials. Based on known effective equations for perfectly conduct…
A Bloch wave numerical scheme for scattering problems in periodic wave-guides
Tomáš Dohnal, Ben Schweizer
We present a new numerical scheme to solve the Helmholtz equation in a wave-guide. We consider a medium that is bounded in the -direction, unbounded in the -direction and…
Strain gradient visco-plasticity with dislocation densities contributing to the energy
Matthias Röger, Ben Schweizer
We consider the energetic description of a visco-plastic evolution and derive an existence result. The energies are convex, but not necessarily quadratic. Our model is a strain gra…
Effective Maxwell's equations in general periodic microstructures
Ben Schweizer, Maik Urban
We study the time harmonic Maxwell equations in a meta-material consisting of perfect conductors and void space. The meta-material is assumed to be periodic with period ; we…
