Augmentation of Integral Equations for Low-Frequency Analysis of Electromagnetic Problems
November 14, 2021 @ 10:00 pm - 11:00 pm
In this talk, the speaker proposes hybrid field integral equations (HFIEs) for describing the EM problems with penetrable media or lossy conductors and extends to augmented HFIEs (AHFIEs) for low-frequency analysis. The HFIEs consist of the EFIE of describing the exterior of the object and the MFIE of describing its interior. Since the magnetic current density appears in the L operator in the HFIEs, we select the magnetic charge density as a new unknown function to be solved and introduce the continuity equation of magnetic current density as an extra equation, in addition to selecting the electric charge density as a new unknown function to be solved and introducing the continuity equation of electric current density as an extra equation in the traditional augmentation. The technique can be applied to the augmentation for all other integral equations including the CFIEs, PMCHWT equations, Müller equations, and VSIEs since the L operator can act on both electric and magnetic current densities. The augmented integral equations are solved by MoM where the RWG and Schaubert-Wilton-Glisson (SWG) basis functions are used to represent the surface current densities of AHFIEs and volume current densities of VIEs, respectively, while a pulse basis function is employed to represent the charge densities of AHFIEs. The complicated DBF is not needed anymore because both the electric and magnetic current densities can be represented by the RWG basis function in the SIEs and resultant system matrices can still be well-conditioned. Numerical examples are presented to illustrate the approach and good results have been obtained.
