Advances in computational electromagnetics

The paper presents a selection of techniques that are currently being investigated at the Technical University of Gdansk and can be used to accelerate CAD of microwave circuits and the computation of high and low frequency electromagnetic fields. Techniques for creating surrogate CAD models and their application to automated design of band pass filters are discussed. Different strategies of electromagnetic field representation for mesh based and meshless methods are introduced and their efficiency illustrated on examples involving structures with complex geometries.
