Unidirectional Wave Propagation in Low-Symmetric Colloidal Photonic-Crystal Heterostructures
Nanomaterials, 2015 We show theoretically that photonic crystals consisting of colloidal spheres exhibit unidirectional wave propagation and one-way frequency band gaps without breaking time-reversal symmetry via, e.g., the application of an external magnetic field or the ...

Single-mode delay time statistics for scattering by a chaotic cavity [PDF]
, 2000 We investigate the low-frequency dynamics for transmission or reflection of a wave by a cavity with chaotic scattering. We compute the probability distribution of the phase derivative phi'=d phi/d omega of the scattered wave amplitude, known as the ...

Medicare 1971: Changing Attitudes and Changing Legislation [PDF]
, 1970 Bone conduction (BC) is the way sound energy is transmitted by the skull bones to the cochlea causing a sound perception. Even if the BC sound transmission involves several pathways including sound pressure induced in the ear canal, inertial forces ...

Design Formulae of Wave Transmission due to Oblique Waves at Low Crested Structures
Jurnal Teknik Sipil, 2011 Low crested structures, including submerged breakwaters, may be provided to protect the beach from wave attack. These structures can be built parallel to the shoreline and the crest is set up at or below water levels. It function is to protect the beach

Coherent control of Snell's law at metasurfaces [PDF]
, 2014 It was recently demonstrated that the well-known Snell's law must be corrected for phase gradient metasurfaces to account for their spatially varying phase, leading to normal and anomalous transmission and reflection of light on such metasurfaces.

Wave Transmission through Trapezoidal Breakwaters
Coastal Engineering 1976, 1976 Previous publications resulting from this study dealt with, certain aspects of the interaction of normally incident waves with a porous structure. Madsen and White (1976a), hereafter referred to as (I), developed a semi-empirical procedure for the prediction of reflection coefficients of rough impermeable slopes. Madsen (1974) with, discussion by Kondo

Quantum versus Classical Dynamics in a driven barrier: the role of kinematic effects
, 2012 We study the dynamics of the classical and quantum mechanical scattering of a wave packet from an oscillating barrier. Our main focus is on the dependence of the transmission coefficient on the initial energy of the wave packet for a wide range of ...
