ABSTRACT

This paper proposes a 3D-to-2D geometry transformation algorithm that significantly decreases the number of computational operations and, as a result, the computation time required for solving complex electromagnetic compatibility problems. The transformation algorithm consists of three steps. In the first step, a matrix of resulting 2D models is formed from the initial 3D problem. The second step consists of synthesizing the solution of the initial 3D problem by sifting out unnecessary elements of the solution image matrix while replacing them at the same time with zeros. Finally, the third step implies the researcher’s return to the initial 3D model, but this time with a decision made about the EMC problem solution, derived from the solution image matrix elements. This decision is built on their comparison with the results obtained with the help of an experimental method, performed on a real object or a real object’s 3D model. Only those elements that are in good agreement with the experimental method results are included in the final decision formulation. A hypothetical aircraft example of electromagnetic compatibility problem computation is given, realized with the help of the finite element method. A corresponding aircraft antenna database has been created.
