Bandgap properties of low index contrast aperiodically ordered photonic quasicrystals
Gianluigi Zito, T. Priya Rose, Emiliano Di Gennaro +3
We numerically analyze, using Finite Difference Time Domain simulations, the bandgap properties of photonic quasicrystals with a low index contrast. We compared 8-, 10- and 12-fold…
Mode Confinement in Photonic Quasi-Crystal Point-Defect Cavities for Particle Accelerators
E. Di Gennaro, S. Savo, A. Andreone +4
In this Letter, we present a study of the confinement properties of point-defect resonators in finite-size photonic-bandgap structures composed of aperiodic arrangements of dielect…
Evidence of local effects in anomalous refraction and focusing properties of dodecagonal photonic quasicrystals
Emiliano Di Gennaro, Carlo Miletto, Salvatore Savo +5
We present the key results from a comprehensive study of the refraction and focusing properties of a two-dimensional dodecagonal photonic ``quasicrystal'' (PQC), carried out via bo…
Pendellosung effect in photonic crystals
S. Savo, E. Di Gennaro, C. Miletto +4
At the exit surface of a photonic crystal, the intensity of the diffracted wave can be periodically modulated, showing a maximum in the "positive" (forward diffracted) or in the "n…
A parametric study of the lensing properties of dodecagonal photonic quasicrystals
E. Di Gennaro, D. Morello, C. Miletto +5
We present a study of the lensing properties of two-dimensional (2-D) photonic quasicrystal (PQC) slabs made of dielectric cylinders arranged according to a 12-fold-symmetric squar…
Linear and nonlinear electrodynamic response of bulk CaC6 in the microwave regime
A. Andreone, G. Cifariello, E. Di Gennaro +5
The linear and nonlinear response to a microwave electromagnetic field of two c-axis oriented polycrystalline samples of the newly discovered superconductor CaC6 (Tc = 11.5 K) is s…
