Abstract

Technique for optimisation of electromagnetic component and sub-system designs based on a cross-entropy method (CEM); with applications in electromagnetic fields such as antenna design; includes evaluating a formulated fitness function for each design in an i-th candidate group of designs sampled from a distribution-of-designs; each design includes multiple design variables characterised by respective i-th probability-distributions represented by an i-th set of distributional -parameters; the formulated fitness function being evaluated based on electromagnetic performance criteria of the corresponding design in the i-th candidate group of designs; and determining an (i+1)-th set of distributional-parameters (representing (i+1)-th probability-distributions characterising the respective multiple design variables) being determined based on a reduction of cross-entropy between an empirical-distribution characterising a selected i-th elite group of designs from the i-th candidate group of designs based on the evaluated fitness function and the (i+1)-th probability-distributions. Each design may include multiple design variables including a discrete and a continuous variable.
