Microwave ovens had a crucial role in the twentieth century. This frequency also sees a lot of application development. Microwave tube advancements have aided numerous growths in the recent past. Based on the RF field phase velocity, microwave tubes can be classed as slow-wave or fast-wave devices. A high-power source and amplifier are necessary for millimetre and sub-millimeter wave applications, which can be obtained by designing fast-wave devices. The interaction of the electron with the RF wave in fast wave tubes differs from slow-wave devices, as will be explained further. A brief history is discussed, as well as the many types of fast-wave tubes and their dispersion relationships.
