Numerical optimization of metallized titania nanotube morphologies for negative index material flat lens applications

We perform numerical calculation in order to optimize the morphology of metallized ti- tania nanotubes from the point of view of flat lens application based on NIM. An efficient multiple-scattering approach is used to calculate propagation of electromagnetic waves through the materials designed. T...
