A paralleled 2-dimensional optimization code is developed by combining the Genetic Algorithm with Particle-In-Cell(PIC) code in order to improve the design of High Power Microwave(HPM) sources. Two HPM sources-Magnetically Insulated Transmission Line Oscillator(MILO) and Superradiance Relativistic Backward Wave Oscillator(SRBWO)-are optimized by using this optimization code. While the beam-wave conversion efficiency is set as optimization goal, the efficiency of optimized MILO is higher than original one by 38.8% with almost the same input power; while the peak output power is set as optimization goal, the peak output power of SRBWO has increased by 37.5% and the beam-wave conversion efficiency has increased by 50%; while the total energy of output wave is the optimization goal, the total energy of output wave of SRBWO has increased by 38.1%. All optimized models obtain reasonable geometry parameters and exact simulating spectra.
