Brass Waveguide Twists are a kind of waveguide component mostly utilized in radio frequency and microwave systems. These types of twists are designed for rotating the polarization of an electromagnetic wave propagating by means of a waveguide. They can be made up of other materials, like aluminum or copper as per their application requirements such as the power level and operating frequency. Brass Waveguide Twists have a section of waveguide, which is twisted along its length. The twist presents a phase shift between the two orthogonal polarization modes of the waveguide, resulting in a cycle of the polarization of the transmitted wave.
