I am thinking about centimeter band radiation and parallel wire filters as a specific example. Suppose there is a regular series of parallel wire filters every fraction of a wavelength for a full wavelength or more. The angular orientation of each filter is rotated by the same constant fraction of a full circle from the orientation of the previous filter.
Will this series of rotating linear filters pass circularly polarized radiation of the proper wavelength and handedness?
If so, does it make a difference if the filters are every quarter of a wavelength, every tenth of a wavelength, or even every one one-hundredth of a wavelength?
