Transverse spin angular momentum (SAM) of photon, also known as ‘photonic wheel’, has attracted much attention, owing to its extraordinary properties and broad application prospect. Thus, it is essential flexibly manipulate the transverse SAM in order satisfy different needs. In this article, we design generate a new kind symmetrically modulated hybridly polarized vector optical field (SM-HP-VO...

In this paper a novel numerical approach is presented for solving the transient incompressible fluid flow problems with free surfaces in generalized two-dimensional curvilinear coordinate systems. Solution algorithm is a combination of implicit real-time steps and explicit pseudo-time steps. Governing fluid flow equations are discretized using a collocated finite-volume mesh. Convective terms a...

This study predicts how the Free Surface Level (FSL) variations around finite length vegetation affect flow structure by using a numerical simulation. The volume of fluid (VOF) technique with Reynolds stress model (RSM) was used for Multizone Hexahedral meshing adopted to accurately track free surface level minimum diffusion at water–air interface. After validation, emergent patches were select...
