Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Display Omitted Expedited multi-objective optimization of expensive electromagnetic (EM) simulation models is addressed.Utilization of variable-fidelity EM models and response surface approximations allow for speeding up the design process.Response correction techniques elevate initial Pareto set to high-fidelity EM model level.Applications for solving problems in microwave and antenna engineering are demonstrated. Vast majority of practical engineering design problems require simultaneous handling of several criteria. For the sake of simplicity and through a priori preference articulation one can turn many design tasks into single-objective problems that can be handled using conventional numerical optimization routines. Hover, in some situations, acquiring comprehensive knowledge about the system at hand, in particular, about possible trade-offs beten conflicting objectives may be necessary.

In this work,  discuss methodologies for expedited multi-objective design optimization of expensive EM simulation models. The solution approaches that  present here rely on surrogate-based optimization (SBO) paradigm, where the design speedup is obtained by shifting the optimization burden into a cheap replacement model (the surrogate). The latter is utilized for generating the initial approximation of the Pareto front representation as ll as further front refinement (to elevate it to the high-fidelity EM simulation model level).  demonstrate several application case studies, including a wideband matching transformer, a dielectric resonator antenna and an ultra-wideband monopole antenna. Dimensionality of the design spaces in the considered examples vary from six to fifteen, and the design optimization cost is about one hundred of high-fidelity EM simulations of the respective structure, which is extremely low given the problem complexity.
