A waveguide polarizer exploiting two different phase shift phenomena is presented in this letter. Iris-type discontinuities are in fact introduced in a waveguide structure having different propagation constants for the two principal polarizations. In

Novel profiled irises for the design of waveguide polarizers are presented. The two degrees of freedom of their piecewise- circular profile allow one to better control the frequency behavior of the differential phase shift. Thanks to this feature, an
