Abstract
Waveguide filters comprising ridges disposed within a waveguide cavity for selecting electromagnetic signals within a frequency passband. An apparatus includes a waveguide filter comprising a waveguide cavity and a plurality of ridges disposed within the waveguide cavity. The apparatus is such that each of the plurality of ridges comprises a first side and a second side, and wherein the first side and the second side are disposed at a non-orthogonal angle relative to one other. The apparatus is optimized for fabrication using metal additive manufacturing techniques.
