Paper Abstract

Reflecting multilayers (ML) are widely used and their linearly polarizing property is well known. In particular an angle of incidence of 45 degree(s) theoretically leads to reflection of only the s-component. Kimura et al. used the phase shifting properties of a reflecting ML to measure circular polarization at 97 eV. A transmitting ML as phase shifting element for the same energy has been described and measured. In this paper we report on the use of a transmission ML as a phase shifting element at photon energies near the carbon K edge. Such devices can have applications in detecting and perhaps generation of circularly polarized soft x-rays.
