Mathematical Model and Numerical Simulation of Aluminum Casting and Solidification in Magnetic Fields with Allowance for Free Surface Dynamics
A complex mathematical model of aluminum casting and solidification in a variable electromagnetic field is constructed. The model is based on the solution of magnetohydrodynamic equations and the VOF method. Test results ...
Localised optical states in a structure formed by two oppositely handed cholesteric liquid crystal layers and a metal
A new model for observing localised optical states in a structure containing a cholesteric liquid crystal is proposed. The dependence of the mode frequency on the angle between directors at the interface of oppositely ...
The optical Tamm states at the interface between a photonic crystal and a nanocomposite containing core–shell particles
Optical Tamm states localized at the edges of a photonic crystal bounded from one or both sides by a nanocomposite have been studied. The nanocomposite consists of metallic nanoinclusions, which have a spherical or ...
Chiral optical Tamm states at the boundary of the medium with helical symmetry of the dielectric tensor
A new optical state is described both analytically and numerically at the boundary of a chiral medium with continuous helical symmetry of the dielectric tensor. The tangential wave number is assumed to be zero. The state ...
Spectral and polarization properties of a ‘cholesteric liquid crystal—phase plate—metal’ structure
We investigate the localized surface modes in a structure consisting of the cholesteric liquid crystal layer, a phase plate, and a metal layer. These modes are analogous to the optical Tamm states. The nonreciprocal ...
