Real life design problems of electromagnetic components are usually highly non-linear. These problems can be efficiently solved with stochastic global optimization algorithms. This paper deals with an application of a novel Multi-objective Self-organizing Migrating Algorithm (MOSOMA) to the design of two electromagnetic components: layered dielectric filters and Yagi-Uda antennas. Optimization of dielectric filters considers two objectives: minimization of reflection in the pass band and its maximization in the stop band. Band-pass, low-pass and band-stop filters having seven dielectric layers are optimized here. An option for treatment of both continuous parameters and discrete ones and dealing with optimization constraints without any change in the optimization algorithm is briefly discussed. Yagi-Uda antenna optimization deals with two-objectives: maximization of gain and minimization of relative side-lobe level, while impedance matching is considered as a constraint for the proposed designs. Yagi-Uda antennas are analyzed using 4NEC2 software based on the method of moments. Co-operation of Matlab optimization script and 4NEC2 software in a non-interactive mode is explained. Results for four- and six-element antennas are presented. Results of both the problems are compared to results from available references.
