Claim:
1. A method comprising: receiving an input signal via a first end of a circular dielectric polarizer having a cylindrical shape, the circular dielectric polarizer comprising: passing the input signal through the circular dielectric polarizer, wherein parameters of the circular dielectric polarizer, the dielectric slab, the dielectric core, and the at least one air cutout cause approximately a 90 degree difference in phase of the input signal as it passes through the circular dielectric polarizer, said parameters including one or more of a thickness of the dielectric slab, a diameter of the circular dielectric polarizer, a length of the circular dielectric polarizer, a width of the at least one air cutout, and an air cutout diameter; and emitting an output signal from a second end of the circular dielectric polarizer, the output signal being phase-shifted by 90 degrees relative to the input signal.
