1. An apparatus comprising:
a waveguide filter comprising a waveguide cavity, wherein the waveguide cavity is defined by a plurality of sidewalls; and
a plurality of ridges disposed within the waveguide cavity;
wherein each of the plurality of ridges is attached to at least one sidewall of the plurality of sidewalls defining the waveguide cavity;
wherein each of the plurality of ridges comprises a first side and a second side connected to the first side, and wherein the first side and the second side of at least one of the plurality of ridges are disposed at a non-orthogonal angle relative to one another; and
wherein only one ridge of the plurality of ridges is attached to any one sidewall of the plurality of sidewalls at any single point along a length of the waveguide cavity.
