20.500.12556/RUL-117981 Physics-based multistep beam propagation in inhomogeneous birefringent media We present a unified theoretical framework for paraxial and wide-angle beam propagation methods in inhomogeneous birefringent media based on a minimal set of physical assumptions. The advantage of our schemes is that they are based on differential operators with a clear physical interpretation and easy numerical implementation based on sparse matrices. We demonstrate the validity of our schemes on three simple two-dimensional birefringent systems and introduce an example of application on complex three- imensional systems by showing that topological solitons in frustrated cholesteric liquid-crystals can be used as light waveguides. optics optika true false true Angleški jezik Slovenski jezik V članku navedeno: "© 2020 Optical Society of America under the terms of the OSA Open Access Publishing Agreement"; s povezavo https://www.osapublishing.org/library/license_v1.cfm.
