Course detail

CAD in Microwaves

FEKT-MCVTAcad. year: 2019/2020

Students become familiar with principles and application of basic numerical methods (finite differences, finite elements, method of moments) for the analysis of microwave structures on frequencies hundreds of MHz up to tens of GHz. Further, standard and non-standard optimization methods (gradient and Newton algorithms, genetic algorithms) and their application to the design of microwave circuits and antennas are described. In frame of an individual project, students will design, manufacture and measure a given planar structure.
