We investigate the plasmonic behavior of a fractal photonic crystal fiber, with Sierpinski-like circular cross-section, and its potential applications for refractive index sensing and multiband polarization filters. Numerical results were obtained us

Plasmonic and magnetic silicon hybrids are suitable hyperthermia nanoagents owing to their ability to generate heat under an external stimulus in addition to their biocompatibility, limited aggregation, dielectric properties, and surface functionaliz

We demonstrate a concept for a large enhancement of the directivity and gain of readily available cm- and mm-wave antennas, i.e., without altering any property of the antenna design. Our concept exploits the high reflectivity of a Bragg reflector com

We present a new proposal for enhancing the transverse magneto-optical Kerr effect (TMOKE) in the transmission mode using dielectric magneto-optical (MO) ribs deposited on a high-refractive-index (HRI) slab. Our concept is based on the phase-matching

We show a strategy to design polarization-insensitive electro-optical modulators based on the use of single-layer graphene sheets working at the e-near-zero (ENZ) regime. An external voltage is used to change the optical properties of graphene at wil

We show here the design of a magnetoplasmonic sensing platform consisting of a bilayer of a transparent conducting oxide and a gold film grown on a ferromagnetic substrate. Near the bulk plasmon fr...

We numerically demonstrate an all-dielectric approach for magnetically tunable add/drop of optical channels in dense wavelength division multiplexing applications. Our concept comprises a micro-ring resonator, with an inner magneto-optical disk, side

A challenge in plasmonic trapping of small nanoparticles is the heating due to the Joule effect of metallic components. This heating can be avoided with electromagnetic field confinement in high-refractive-index materials, but nanoparticle trapping i
