Abstract
Metamaterials are usually composed of periodic arrays of inclusions embedded in layered media. Their full-wave numerical characterisation with integral-equation formulations generally requires the accelerated computation of multilayered periodic Green's functions. An efficient strategy is presented here, able to solve plane-wave incidence problems and carry out rigorous dispersive analyses of two-dimensional structures with periodic cylindrical-type inclusions. Asymptotic terms are extracted from the relevant spectral series and are accelerated with the Ewald method, after suitable modifications depending on the Green's function component under analysis. © 2011 EurAAP.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
