Abstract: A consistent time-domain methodology for the systematic design and
broadband assessment of complicated nanostructured EMC devices is introduced in
this paper. The novel technique combines a family of nonstandard locally
one-dimensional finite-difference time-domain schemes with the advanced
features of contemporary graphics processor units in general curvilinear
coordinates which preserve the hyperbolic profile of Maxwell's laws. In this
way, the resulting formulation remains completely explicit and generates
effective dual meshes free of artificial vector parasites or spurious modes,
while the frequency-dependent attributes of every setup are successfully
modelled. Numerical results reveal the significant reduction of dispersion
errors along with the considerable speedup compared to serialised realisations
through various fabric/epoxy devices with nanocomposite media.
