The latter are assumed to scatter like dipoles. A numerical approach is extended to account for the influence of the lattice with more precision. This is done by a simple extrapolation scheme, which accelerates the convergence of the arising series. For regular arrays, a comparison with a commercial software tool reveals a good agreement, at least as long as the distance between the particles is large enough for the dipole assumption to be valid. This also applies at resonance, the most critical case. The effects on random arrays are also investigated. © 2007 Wiley Periodicals, Inc.en0895-247720071026092613WileyElectromagnetic scatteringHelicesPeriodic structuresSimulationTechnikIngenieurwissenschaftenJournal Article10.1002/mop.22788Other
