Abstract :
This paper describes the peculiarities of mode converters of coaxial cavity gyrotrons. The high order and the characteristic field pattern of these modes makes it difficult to design a quasi-optical mode converter with a dimpled wall launcher and (possibly) Yeti-footprint-mirrors. Methods and design strategies to overcome these difficulties are presented.
