Claim 2:
3. The method of claim 1, where each omnidirectional circular-polarized wave has an excitation amplitude and phase, further comprising:
for each omnidirectional circular-polarized wave in the plurality of omnidirectional circular-polarized wave:
exciting a first circular TEn1 mode, where n is an integer number greater than or equal to 1 representing the mode number;
exciting a second circular TEn1 mode that is a degenerate mode of the first circular TEn1 mode and is spatially rotated relative to the first circular TEn1 mode by 180 degrees/(2n), and that has an excitation phase difference of 90 degrees; and, controlling the excitation amplitude and phase in a way that forms and steers the beam.
