| Abstract: | In this paper,based on a research on the integrating of genetic algorithms(GA) and neural network(NN),and using them in the optimization of single-circuit negative prAmeability material with a shape of Chinese character ju,we picked some samples by orthogonal experiment method and calculated the performance parameter with high frequency structure simulator(HFSS) and output the results,and then established the BP neural network model using the former results by HFSS to map the relation between the structure ... |
