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…
Directive Emission from Defect-Free Dodecagonal Photonic Quasicrystals: A Leaky-Wave Characterization
Alessandro Micco, Vincenzo Galdi, Filippo Capolino +4
In this paper, we study the radiation from embedded sources in two-dimensional finite-size "photonic-quasicrystal" (PQC) slabs made of dielectric rods arranged according to a 12-fo…
LIGO: The Laser Interferometer Gravitational-Wave Observatory
The LIGO Scientific Collaboration, B. Abbott
The goal of the Laser Interferometric Gravitational-Wave Observatory (LIGO) is to detect and study gravitational waves of astrophysical origin. Direct detection of gravitational wa…
Perspectives on Beam-Shaping Optimization for Thermal-Noise Reduction in Advanced Gravitational-Wave Interferometric Detectors: Bounds, Profiles, and Critical Parameters
Vincenzo Pierro, Vincenzo Galdi, Giuseppe Castaldi +3
Suitable shaping (in particular, flattening and broadening) of the laser beam has recently been proposed as an effective device to reduce internal (mirror) thermal noise in advance…
Upper limits on gravitational wave emission from 78 radio pulsars
The LIGO Scientific Collaboration, B. Abbott, M. Kramer +1
We present upper limits on the gravitational wave emission from 78 radio pulsars based on data from the third and fourth science runs of the LIGO and GEO600 gravitational wave dete…
