【Abstract】 In terms of the Genetic algorithm (GA), the propagating constant of the rectangular waveguide partially filled with dissipative magnetic materials is accurately calculated and particularly analyzed. A new algorithm is formed by combining the robust function of GA with the compressing and moving of searching-area in the parameter tracking scheme, in which the searching area is decreased, solution is simplified and the calculating speed is accelerated due to the parameter tracking The precision of the results is enhanced due to the dynamic searching area. The predicting of the new searching center by the application of a 3-order difference formula speeds up the calculation further. The practical results show that the method in this paper is especially efficient and accurate.
