Though many failure modes cannot be predicted or avoided, many of the common failure modes of waveguide assemblies can be avoided by properly accounting for the applications demands and running preventative maintenance programs. If the outer coating/jacket of a waveguide cable run is important in preventing environmental ingress, visual and chemical inspections can be performed ..

The quality of the construction and materials used can have a large impact on the performance of a waveguide system, especially in microwave frequencies and high power applications. This can become difficult to manufacture and evaluate, as the waveguide tolerances are extremely small at microwave and millimeter-wave frequencies. For instance, with millimeter-wave components and interconnects, ..

Though waveguide components and interconnects tend to be formed of relatively sturdy metals, some aluminum and copper waveguides, for higher frequency and aerospace applications, can easily be dinged and dented. Sometimes these dings and dents are a useful tuning technique; generally, they could dramatically change the performance of a waveguide or waveguide component. Ensuring that ..
