Metamaterial-induced-transparency engineering through quasi-bound states in the continuum by using dielectric cross-shaped trimers
Maryam Ghahremani, Carlos J. Zapata-Rodriguez
This study presents a novel approach to activate a narrowband transparency line within a reflecting broadband window in all-dielectric metasurfaces, in analogy to the electromagnet…
Out-of-plane emission of trions in monolayer WSe2 revealed by whispering gallery modes of dielectric microresonators
D. Andres-Penares, M. K. Habil, A. Molina-Sánchez +3
The manipulation of light emitted by two-dimensional semiconductors grounds forthcoming technologies in the field of on-chip communications. However, these technologies require fro…
Lasing condition for trapped modes in subwavelength--wired PT--symmetric resonators
Mauro Cuevas, Mojtaba Karimi, Carlos J Zapata-Ropdriguez
The ability to control the laser modes within a subwavelength resonator is of key relevance in modern optoelectronics. This work deals with the theoretical research on optical prop…
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…
