Bound states in the radiation continuum and a resonant generation of second harmonics in double arrays of subwavelength dielectric cylinders
Bound states radiation continuum subwavelength dielectric cylinder second harmonics
2011/8/24
Abstract: A nonlinear electromagnetic scattering problem is studied for two parallel periodic arrays of dielectric cylinders with a second order nonlinear susceptibility. For a wide range of values of...
Researchers in the US have built the first practical device that can cloak an object from being detected by sound waves. The cloak, which is made from a cylindrical array of acoustic cavities, has bee...
The Twente Turbulent Taylor-Couette (T3C) facility: strongly turbulent (multi-phase) flow between two independently rotating cylinders
Taylor-Couette (T3C) facility rotating cylinders
2010/11/16
A new turbulent Taylor-Couette system consisting of two independently rotating cylinders has been constructed. The gap in between the cylinders has a height of 0.927 m, an inner radius of 0.200 m and...

The tilt angle profile in a nematic cell limited by two concentric cylindrical surfaces with inhomogeneous distribution of easy axes is investigated in the one-constant approximation. The results are ...
Study of Effects of Interfaces in the Propagation of the Energy by Optical Modes in Coaxial Cylinders
Cylindrical interface Polaritons in Cylindrical structures Localized polaritons
2010/9/29
We study the influence of the interfaces on the dispersion relation, energy and power flow of polaritons propagating in coaxial cylinders. We consider an infinite coaxial cylinder of internal and exte...
