Design optimization of complex electromagnetic devices such as antennas with volumetric material and conductor variations require high computational resources. This burden can be reduced by introducing cost-effective surrogate models into the design optimization framework. Here we present a comparative analysis of various surrogate modeling techniques for material design studies of electromagnetic devices. Also a new polynomial based approximation technique is proposed for modeling frequency based responses of complex electromagnetic devices especially exhibiting multi-resonance behavior.
