Abstract
A method and apparatus for changing the polarization of an input signal includes propagating a polarized input signal having orthogonal E-field components by at least one surface each having a respective surface impedance and varying at least one of the surface impedances to shift the phase of one of the components independently from the other so that the polarity of said input signal is changed. Bi-directional propagation is achieved by rotating polarity in one direction but not the other.
