Abstract
Methods, systems, and devices are described that include one or more sidewall features to improve performance of a waveguide device. In particular, the sidewall features may be utilized within a polarizer section of a polarizer device such as a septum polarizers. The sidewall feature(s) may include recesses and/or protrusions. When a plurality of sidewall features are employed, the size, shape, spacing and kind (e.g., recess or protrusion) may vary according to a particular design.

A waveguide device, comprising:
- a common waveguide section;
- a divided waveguide section having a first divided waveguide associated with a first basis polarization and a second divided waveguide associated with a second basis polarization;
- a polarizer section coupled between the common waveguide section and the divided waveguide section, the polarizer section comprising a central axis in a direction between the common waveguide section and the divided waveguide section, a first set of opposing sidewalls, a second set of opposing sidewalls, and a septum extending between the opposing sidewalls of the first set and forming a boundary between the first and second divided waveguides;
- and
- at least one sidewall feature on at least one sidewall of the first set of opposing sidewalls, wherein the at least one sidewall feature is coincident with the septum along the central axis of the polarizer section.
