GA-optimization approach to remove the noise due to the resonance mode of the slit parallel-plate structure

An efficient method is presented to remove the noise source in the communication system such as mobile phones where the parallel-plate structure(PPS) resides. With the help of an exact EM solver and Genetic Algorithm(GA), the proper geometrical change using the slit is sought to damp the target resonance mode. This brings us the effective means to suppressing the noise. And in particular, given the limitations in the physical dimension of the PPS without resorting to the conventional lumped element like DeCaps we can cope with the resonance phenomena. The suggested method’s validity will be proven by the agreeable measurement and other examples.
