Abstract

We outline specific features of numerical simulations of metamaterial wedges and interfaces. We study the effect of different positioning of a grid in the Yee method, which is necessary to obtain consistent convergence in modelling of interfaces with metamaterials characterized by negative dielectric permittivity and negative magnetic permeability. We demonstrate however that, in the framework of the continuous‐medium approximation, wave scattering on the wedge may result in a resonant excitation of waves with infinitely large spatial frequencies, leading to non‐convergence of the simulation results that depend on the discretization step.

Fields scattered by a lossy dielectric wedge for a plane-wa¨e incidence are calculated. Reflected and refracted fields are obtained by inhomogeneous plane-wa¨e tracing in a lossy medium, while the edgediffracted fields of the physical-optics approximation are accurately corrected by adding the multi

## Abstract A UV multilevel partitioning method (UV‐MLP) is developed to solve the volume‐scattering problem. The method involves creating a rank table of transmitting and receiving block sizes and their separation. The table can be set up speedily using coarse‐coarse sampling. For a specific scatt

## Abstract We consider the direct interaction problem describing the scattering of acoustic waves by an elastic obstacle with interior cracks. By the potential method we reduce the problem to an equivalent system of integral (pseudodifferential) equations and study its solvability. In particular,
