Electromagnetic tunneling through a single-negative slab paired with a double-positive bi-layer
Giuseppe Castaldi, Ilaria Gallina, Vincenzo Galdi +2
We show that resonant tunneling of electromagnetic fields can occur through a three-layer structure composed of a single-negative (i.e., either negative-permittivity or negative-pe…
Analytical study of spherical cloak/anti-cloak interactions
Giuseppe Castaldi, Ilaria Gallina, Vincenzo Galdi +2
The intriguing concept of "anti-cloaking" has been recently introduced within the framework of transformation optics (TO), first as a "countermeasure" to invisibility-cloaking (i.e…
Experimental evidence of cut-wire-induced enhanced transmission of transverse-electric fields through sub-wavelength slits in a thin metallic screen
Emiliano Di Gennaro, Ilaria Gallina, Antonello Andreone +2
Recent numerical studies have demonstrated the possibility of achieving substantial enhancements in the transmission of transverse-electric-polarized electromagnetic fields through…
Experimental evidence of guided resonances in photonic crystals with aperiodically-ordered supercells
Armando Ricciardi, Marco Pisco, Ilaria Gallina +5
We report on the first experimental evidence of guided resonances (GRs) in photonic crystal slabs based on aperiodically-ordered supercells. Using the Ammann-Beenker (quasiperiodic…
Tuning efficiency and sensitivity of guided resonances in photonic crystals and quasi-crystals: A comparative study
Marco Pisco, Armando Ricciardi, Ilaria Gallina +5
In this paper, we present a comparative study of the tuning efficiency and sensitivity of guided resonances (GRs) in photonic crystal (PC) holed slabs based on periodic and aperiod…
Transformation-optics generalization of tunnelling effects in bi-layers made of paired pseudo-epsilon-negative/mu-negative media
Giuseppe Castaldi, Ilaria Gallina, Vincenzo Galdi +2
Transformation-media designed by standard transformation-optics (TO) approaches, based on real-valued coordinate-mapping, cannot exhibit single-negative (SNG) character unless such…
