Use of a Genetic Algorithm in Modelling Small Structures in Airframes: Characterising and modelling joints, seams, and apertures

Research output: Chapter in Book/Report/Conference proceedingConference contribution


In this paper, a Genetic Algorithm (GA) is used to build macro models of small structures, such as joints and apertures, for use in large-scale computer simulations for aircraft electromagnetic compatibility (EMC) testing and certification. The field penetrating the structure is approximated by radiated fields of electric and magnetic dipole moment array. A GA is applied to determine the dipole moment array that produces the same effect as the structure that is to be built into the model. A scanning frame and a magnetic field probe have been constructed to measure the fields in the vicinity of the small structure, to provide field data for the fitting process.
