Parametric optimization of protective meander line turn in air filling by genetic algorithm

One-criterion parametric optimization by genetic algorithm (GA) of air protective meander line turn cross-section is executed. For this task the quality function which provides geometric mean of wave impedances for even and odd modes of the line (Z) to be equal to the 50 Ω is formulated. All of 4 cross-section parameters of the investigated structure are simultaneously optimized. The results of 5 GA runs with 10 and 100 generations of 30 individuals are described. Well reproducibility of Z value around the value of 50 Ω with deviation less than 0.1% is demonstrated. The optimization time costs were estimated. The source code of the program (in TALGAT software) is presented in Appendix.
