Zusammenfassung:Low-rank approximation techniques are useful approaches to reduce the computational effort required by integral equations methods. Here, two different libraries based on hierarchical-matrices and hierarchically semi-separable matrices are applied to the partial element equivalent circuit method for the study of high-frequency electromagnetic problems. The academic case of a dielectric sphere and the study of a complex device used in thermonuclear fusion science are considered in order to compare the performances of the two libraries.
