There are four sub-populations (or parallel processes) in the coarse-grained PMGA. Fig.
A VBA macro language is used to combine the coarse-grained PMGA and CST MWS.
Table 1 shows the parameters of the PMGA on each subpopulation.
The design parameters for the UWB power divider obtained by the coarse-grained PMGA are shown in Table 2.
Table 3 shows the design parameters of the UWB power divider optimized by the coarse-grained PMGA. The optimized isolation resistors in the table are replaced by their nearest standard chip resistors.
The power divider was optimized using the coarse-grained PMGA combined with a numerical solver CST MWS.
