Characterization of beam splitters in the calibration of a

Beam splitters are one of the most critical optical components in a splitting optical system, which can be mainly divided into two categories: polarization beam splitter (PBS), and non-PBS (NPBS). An ideal PBS can separate the s-component from the p-component in the incident light [1], while an ideal

The results show that two components are asymmetric due to the cross-polarization of the electromagnetic fields in chiral slab. By adjusting the angle of incidence and the polarization state of the incident beam, the spatial splitting can be enhanced.

Beam forming and beam scanning are generally accomplished by phasing the feed to each element of an array so that signals received or transmitted from all elements will be in phase in a particular direction. This is the direction of the beam maximum. Beam forming and beam scanning techniques are typically used with linear, circular, or planar
