A novel hybrid hierarchy genetic algorithm was introduced through combining hierarchy genetic algorithm and least square method. This hybrid algorithm could determine the structure and parameters of the radial basis function neural network,and the program is implemented using MATLAB language. This neural network is then applied to the modeling of the microstrip defected ground structure,and the transmission coefficient of the microstrip defected ground structure can be obtained from the neural network model...
