Abstract

The invention discloses a rapid optimization design method applied to a millimeter wave extended interaction oscillator, and relates to the technical fields of microwave, millimeter wave and terahertz electric vacuum devices. This method adopts repeated iterative optimization of simulation-numerical-simulation, and combines nonlinear numerical calculation into multi-parameter optimization, so as to achieve the optimization goal of the highest interaction efficiency more quickly; according to the theoretical analysis and optimization calculation results, it is described in a unified expression form The relationship between the electric field amplitude distribution of each gap in the optimal interaction high-frequency structure; then, according to the proposed electric field expression form, the optimization of the high-latitude dimension can greatly reduce the dimension, reduce the variation range of the optimization parameters, and finally greatly reduce the Small optimization time and improved optimization results; in addition, compared with the nonlinear numerical calculation program calculated with time step, the nonlinear self-consistent solution of the injection-wave interaction with space step and the optimization method of simulated annealing algorithm are used to calculate the numerical value. The calculation process is faster and the results are more stable.
