Abstract

Here we report on the holistic development of highly overmoded slow-wave circuits (SWCs) for millimeter-wave (MMW) and terahertz (THz) radiation sources. Transmission and oscillatory characteristics of a quasi-TM04 mode SWCs have been obtained by a mode conversion circuit from a rectangular waveguide TE10 mode to circular waveguide TM01 mode. The design of a 0.3 THz oscillator with a conservative output power of 60 W is demonstrated with this quasi-TM04 mode SWCs in a cylindrical cavity with an inner diameter of 4.16 mm. The results show that using MMW engineering circuit sizes has the potential to emit higher THz frequency electromagnetic radiation, which provides a new technological horizon to overcome a variety of engineering challenges caused by the desire for increasing operational frequencies.
