Effective Electromagnetic Wave Properties of Disordered Stealthy Hyperuniform Layered Media Beyond the Quasistatic Regime
Jaeuk Kim, Salvatore Torquato
Disordered stealthy hyperuniform dielectric composites exhibit novel electromagnetic wave transport properties in two and three dimensions. Here, we carry out the first study of th…
Sub-diffusive wave transport and weak localization transition in three-dimensional stealthy hyperuniform disordered systems
Fabrizio Sgrignuoli, Salvatore Torquato, Luca Dal Negro
The purpose of this work is to understand the fundamental connection between structural correlations and light localization in three-dimensional (3D) open scattering systems of fin…
Gap Sensitivity Reveals Universal Behaviors in Optimized Photonic Crystal and Disordered Networks
Michael A. Klatt, Paul J. Steinhardt, Salvatore Torquato
Through an extensive series of high-precision numerical computations of the optimal complete photonic band gap (PBG) as a function of dielectric contrast for a variety of cryst…
Effects of Random Link Removal on the Photonic Band Gaps of Honeycomb Networks
Marian Florescu, Salvatore Torquato, Paul J. Steinhardt
We explore the effects of random link removal on the photonic band gaps of honeycomb networks. Missing or incomplete links are expected to be common in practical realizations of th…
Complete Band Gaps in 2D Photonic Quasicrystals
Marian Florescu, Salvatore Torquato, Paul J. Steinhardt
We introduce a novel optimization method to design the first examples of photonic quasicrystals with substantial, complete photonic band gaps (PBGs): that is, a range of frequencie…
Designer disordered materials with large complete photonic band gaps
Marian Florescu, Salvatore Torquato, Paul J. Steinhardt
We present designs of 2D isotropic, disordered photonic materials of arbitrary size with complete band gaps blocking all directions and polarizations. The designs with the largest…
