Abstract:
We propose that waveguides structures may transform an incident unpolarized beam into a polarized microbeam and while also be used a spin-flippers by varying the incidence angle on the structure. We describe optimized structures combining these functions. Such waveguides could be used for the investigation of one-dimensional magnetic structures and could be implemented on any existing fixed wavelength reflectometer.
