With rapid advancement in data acquisition technology (i.e.analog-to-digital and digital-to-analog converters) and the explosive introduction of micro-computers, selected complex linear and nonlinear ...

Angular spectrum methods constitute a powerful framework for simulating wave propagation and diffraction phenomena in optical systems. By decomposing a complex wavefield into its constituent plane ...

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. Their study not only identifies the constraints of conventional sampling ...
