Nonlinear hyperlens
D Aronovich, G Bartal - Optics Letters, 2013 - opg.optica.org
The performance of an optical hyperlens made of metal–dielectric layers can be improved
by incorporating self-focusing nonlinearity in the dielectric layers. Using a modified beam …

Higher-order wide-angle split-step spectral method for non-paraxial beam propagation
We develop a higher-order method for non-paraxial beam propagation based on the wide-
angle split-step spectral (WASSS) method previously reported [Clark and Thomas, Opt …
