ANALYSIS AND OPTIMIZATION OF THE SANDWICHED METAL-DIELECTRIC POLARIZING BEAM SPLITTER GRATING

A reflective sandwiched polarizing beam splitter (PBS) grating with a connecting layer in Littrow mounting is described and designed in this paper.By using two-beam-interference theory for a modal method, a duty cycle and a period of grating Roach Clip can be calculated, where the first order is well suppressed for transverse magnetic (TM) polariza

BackgroundMaternal undernutrition is the most common cause of fetal growth restriction (FGR) worldwide.FGR increases morbidity and mortality during infancy, as well as contributes to adult-onset diseases including obesity and type 2 diabetes.The role of the maternal or offspring microbiome in growth outcomes following FGR is not well understood.Met
