Metacoatings for wavelength scale, high NA plano-concave focusing lenses
Mahin Naserpour, Carlos J. Zapata-Rodríguez, Carlos Díaz-Aviñó +1
We design plano-concave silicon lenses with coupled gradient-index plasmonic metacoatings for ultrawide apertured focusing utilizing a reduced region of . The anomalou…
Optimization of multilayered nanotubes for maximal scattering cancellation
Carlos Díaz-Aviñó, Mahin Naserpour, Carlos J. Zapata-Rodríguez
An optimization for multilayered nanotubes that minimizes the scattering efficiency for a given polarization is derived. The cylindrical nanocavities have a radially periodic distr…
Tunable scattering cancellation of light using anisotropic cylindrical cavities
Carlos Díaz-Aviñó, Mahin Naserpour, Carlos J. Zapata-Rodríguez
Engineered core-shell cylinders are good candidates for applications in invisibility and cloaking.In particular, hyperbolic nanotubes demonstrate tunable ultra-low scattering cross…
Conditions for achieving invisibility of hyperbolic multilayered nanotubes
Carlos Díaz-Aviñó, Mahin Naserpour, Carlos J. Zapata-Rodríguez
Highly-anisotropic plasmonic nanotubes exhibit a dramatic drop of the scattering cross section in the transition regime from hyperbolic to elliptic dispersion. The characterization…
