Theory and conceptual design of a high-power highly efficient magnicon at 10 and 20 GHz

It is shown that magnicons can be scaled up to high frequency (X-band and above) at high power and efficiency. Magnicons have an advantage over other slow wave devices in that the structure sizes are comparable to or larger than a wavelength, so RF breakdown should be less of a problem. However, they require higher voltage. The magnicon has the promise of considerably enhancing the technology of efficient high-power high-frequency RF sources
