Ray representation method of gyrotron quasi-optical output system

The invention discloses a ray representation method of a gyrotron quasi-optical output system, and relates to the microwave technology. The method comprises the following steps of: a) determining an incident light angle; b) selecting the curved surface shape of two mirror reflectors; c) orderly placing the first mirror reflector and the second mirror reflector on an output light path of a gyrotron radiator; d) converting the propagation characteristics of a millimeter wave beam on the first mirror reflector and the second mirror reflector into a light propagation process of a light ray on the first mirror reflector and the second mirror reflector; e) charting the reflected propagation path of the light ray in a first mirror reflector and second mirror reflector conversion system; f) according to the propagation path chart formed in the step e), guiding design and rectification of the curved surface of the reflector of a quasi-optical mode converter, and finishing. The representation method provided by the inv
