Transformation optics from macroscopic to nanoscale

1.Introduction.Transformation optics (TO) is an emerging technique for the design of advanced electromagnetic (EM) media.It is based on the concept that Maxwells equations can be written in a form-invariant manner under coordinate transformations,such that only the permittivity and permeability tensors are modified.1 3 With the coordinate transformation applied to the constitutive [1006.3364] Generalized Transformation Optics of Linear Jun 17,2010·This approach,which generalizes the Plebanski based approach,is systematically applicable for all transformations and all general linear materials.Importantly,it enables useful applications such as arbitrary relative motion,transformations from arbitrary non-vacuum initial dielectric media,and arbitrary space-times.
