Claim 0:
1. A method for emitting a signal from an antenna to a desired configurable direction, comprising:
exciting multiple circular TEn1 modes and their degenerate modes to create a plurality of superposed omnidirectional circular-polarized waves, including a first omnidirectional circular-polarized wave with a first azimuthal wave profile and a second omnidirectional polarized wave with a second azimuthal wave profile, where the first azimuthal wave profile depends on an excited mode number n=1 and its degenerate mode, and where the second azimuthal wave profile depends on the excited mode number n=2 and its degenerate mode, and
where a difference between the first azimuthal phase profile and the second azimuthal phase profile is leveraged to create a directional and steerable circularly polarized beam.
