Synthesis of array near to PEC platform by using UV/MoM-PO hybrid method and GA approach

An optimization process based on genetic algorithm (GA) and UV accelerating method of moment/physical optical hybrid method (UV/MoM-PO) is presented in this paper for the synthesis of the array antennas located near to electric-large scale PEC body. In this work, the geometric size and position of the array are invariable and the amplitude and phase distribution of the excited voltage for the array are considered as the optimized parameters. The UV/MoM-PO method is adopted as the forward computation algorithm to obtain the pattern of the array accounting for the effects of the platform, while the GA is used as the optimization method. Finally, two examples are given to demonstrate the optimization process.
