  • Abstract
    This paper presents a low-frequency stable finite element formulation in terms of the electric fiel and the magnetic flu density for the modal analysis of waveguides. In contrast to competing methods, the eigenvalues of the proposed formulation represent propagation coefficient rather than their squares, which allows to resolve solutions close to zero more accurately.
