Abstract:

The implicit space mapping(ISM) algorithm and the method of moments(MoM) are combined to achieve the array pattern synthesis and improve the optimization efficiency. In the process of optimization, the MoM models with simple and complex mesh subdivision are used as the ISM coarse model and fine model, respectively. The feed amplitude or phase is selected as the auxiliary parameter and the differential evolution(DE) algorithm is used in the process of parameter extraction to achieve the approximation from coarse model to fine model. Finally, three optimization examples for amplitude, phase, and element spacing are presented. The results show that the implicit space mapping algorithm can effectively improve the optimization speed and complete the pattern synthesis.

Key words: implicit space mapping, method of moments, differential evolution, pattern synthesis
