Surface plasmons are able to generate extremely strong and confined optical fields at a deep-subwavelength scale, far beyond the diffraction limit, and now play a central role in nanosciences. A proper combination of plasmonic nanostructures can support Fa ...
Plasmonic metamaterials based on metal-dielectric nanostructures exhibit unique optical properties such as high near-field enhancement, negative refractive indexing, and optical cloaking. In this paper, we present a plasmonic multiband metamaterial based o ...
In this paper, an overview of recent theoretical investigations and experimental characterization of the electromagnetic fields in the vicinity of a tower struck by lightning is presented. The presence of an elevated strike object has been included in two ...
We identify a route towards achieving a negative index of refraction at optical frequencies based on coupling between plasmonic waveguides that support backwards waves. We show how modal symmetry can be exploited in metal-dielectric waveguide pairs to achi ...
We investigate an air-slot photonic crystal cavity for high-precision refractive index sensing. The high quality factor ∼2:6 × 10^4 of the cavity, along with a strong overlap between the resonant mode and the hollow core region, allows us to achieve an exp ...
The simulation, fabrication and characterization of a metallic slot grating on a silicon waveguide (30 nm slot width for a period of 500 nm) are presented [1]. This device is attempting to be a sensor for refractive index variation measurements with theore ...

The optical properties of plasmonic nanostructures supporting Fano resonances are investigated with an electromagnetic theory. Contrary to the original work of Fano, this theory includes losses in the materials composing the system. As a result, a more gen ...
Multilayered media with printed circuits embedded between their dielectric layers are one of the most successful technologies for manufacturing planar structures with a very promising performance-to-price ratio. These planar structures include many differe ...
Suspected to produce harmful consequences on health, the effects of electromagnetic fields of power lines have been extensively studied in the last 30 years. The paper will present a review of epidemiological and experimental studies performed in different ...
There has been a very strong development of the sensors based on surface plasmon resonance during the last thirty years, mostly for biological and biomedical applications. If the first experiments in this field were carried out at the beginning of the 20t ...
