Generation of optical vortices by using spiral phase plates made of polarization dependent devices
Optics Letters
|April 2, 2014
Abstract:
A method to construct spiral phase plates (SPPs) from quarter-wave plates and spatially variable half-wave plates (SVHWPs) is proposed. Optical vortices were experimentally generated by using SPPs made of polarization-dependent devices. The topological charge of the optical vortex can be also determined by the structure of the SVHWP and the polarization of the incident beam.

01:21Generation of Three-Phase Voltage
1.1K
A three-phase AC generator has a rotor with a rotating magnet placed within the stator mounted with the stationary three-phase winding to generate three-phase voltages via mutual induction. These windings are evenly distributed around the inner circumference of the stator and are arranged 120 electrical degrees apart. Three-phase stator windings consist of three separate coils or groups of coils, known as phases, each connected in Y (star) configuration or Delta configuration.

01:17Steady, Laminar Flow Between Parallel Plates
1.1K
Understanding steady, laminar flow between parallel plates is essential for analyzing and designing flow in narrow rectangular channels, commonly found in various water conveyance and drainage systems. The Navier-Stokes equations govern fluid motion and are generally challenging to solve due to their nonlinearity. However, simplifications are possible in certain cases, like the steady laminar flow between parallel plates. For this scenario, we assume steady, incompressible, laminar flow.
