Multilayered wire-grid polarizers (WGP) find application as low-reflection polarizers in projection-type liquid crystal display devices. We describe a design method for multilayered WGPs based on a monochromatic recursive convolution finite-difference time-domain algorithm. The goal is to identify suitable materials and thicknesses for the additional layers… (More)
SUMMARY We designed multilayer wavelength-selective reflector films by stacking thin-films of transparent polymer. The optimum structure of the multilayer is determined using a combination of characteristic matrix method and a version of genetic algorithm. Such multilayer films can be used in LCD devices to enhance the color saturation of the display.
Magnetic levitation is a popular topic of research over the years throughout the world due to its wide range of industrial applications. In any DC attraction type suspension system, actuator and guide-way (rail) plays most important role. In this manuscript FEM based analysis of different structures of actuator and rail (guide-way) has been carried out… (More)
