We study the polarization structures in the vicinity of C-lines in the near fields diffracted from a pair of small holes. We find that, when the incident light is circularly polarized, both the true C-lines and the structures near them are controlled only by the longitudinal component. Furthermore, we find that all the existing singular lines of circular(More)
Physiological effects caused by power ultrasound radiation are of therapeutic benefits for fracture healing. However, these effects are hard to detect with current instrumentations. The aim of this paper is to analyze the behavior of bone subject to therapeutic ultrasound and provide data reference for an intelligent bone ultrasonic system. In this paper,(More)
In this paper, we show that arrayed polarization singularities (PSs) can be generated by interference of three polarized waves. An experimental setup was proposed and used to produce one of the available types of array structures. We then analytically identified factors that control the structures of these arrays and classified all the structures into three(More)
