Abstract:
A polarizer includes a waveguide channel having a substantially square cross section and a septum disposed within the waveguide channel. The septum includes a stepped edge and two opposite stepped surfaces. The stepped surfaces are sectionally recessed toward each other along the direction pointing toward the interior of the waveguide channel, wherein the number of the steps of the stepped surface is greater than two, but smaller than the number of the steps of the stepped edge. In one embodiment, the square cross section may include a plurality of rounded corners and a plurality of edges extending correspondingly between the rounded corners, wherein the ratio of the radius of the rounded corner to the distance between two opposite edges is in a range of from 0.05 to 0.3.
