Scattering of electromagnetic waves from a graphene-coated thin cylinder of left-handed metamaterial
Hamid Pashaeiadl, Mahin Naserpour, Carlos J. Zapata-Rodriguez
In this paper we explored the scattering behavior of thin cylinders made of LHM and coated by a monoatomic graphene layer. A spectral tunability of the resonance peaks is evidenced…
Accurate expansion of cylindrical paraxial waves for its straightforward implementation in electromagnetic scattering
Mahin Naserpour, Carlos J. Zapata-Rodriguez
The evaluation of vector wave fields can be accurately performed by means of diffraction integrals, differential equations and also series expansions. In this paper, a Bessel serie…
Plano-concave microlenses with epsilon-near-zero surface-relief coatings for efficient shaping of nonparaxial optical beams
Mahin Naserpour, Carlos J. Zapata-Rodriguez, Mahdieh Hashemi
Epsilon-near-zero (ENZ) materials, including artificial metamaterials, have been advanced to mold laser beams and antenna-mediated radiated waves. Here we propose an efficient meth…
Tunable invisibility cloaking by using graphene-coated nanowires
Mahin Naserpour, Carlos J. Zapata-Rodriguez, Slobodan M. Vukovic +1
We investigate, both theoretically and numerically, a graphene-coated nano-cylinder illuminated by a plane electromagnetic wave in THz range of frequencies. We have derived an anal…
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

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…
Dyakonov surface waves in lossy metamaterials
A. J. Sorni, M. Naserpour, C. J. Zapata-Rodríguez +1
We analyze the existence of localized waves in the vicinities of the interface between two dielectrics, provided one of them is uniaxial and lossy. We found two families of surface…
Light capsules shaped by curvilinear meta-surfaces
Mahin Naserpour, Carlos J. Zapata-Rodriguez, A. Zakery +1
We propose a simple yet efficient method for generating in-plane hollow beams with a nearly-full circular light shell without the contribution of backward propagating waves. The me…
Nonparaxial shape-preserving Airy beams with Bessel signature
Carlos J. Zapata-Rodriguez, Mahin Naserpour
Spatially accelerating beams that are solutions to the Maxwell equations may propagate along incomplete circular trajectories, after which diffraction broadening takes over and the…
