DOI: 10.1109/lawp.2020.2990177

Abstract: A skeletonization scheme is proposed to accelerate the evaluation of scattering/radiation fields. The proposed scheme performs well for targets with multiscale feature as well as scenarios where multiple excitations are involved. Numerical experiments on targets… read more here.

DOI: 10.1109/lawp.2023.3333406

Abstract: A domain decomposition method is presented for analyzing electromagnetic problems involving multiple nonoverlapping scatterers or electrically large scatterers. We first construct a sparse or simple-to-invert impedance matrix that does not account for partial mutual coupling.… read more here.

DOI: 10.1109/tmtt.2023.3330766

Abstract: This article proposes a novel electromagnetic (EM) parametric modeling approach using model-order reduction (MOR)-based neuro-impedance matrix transfer functions (neuro-IMTFs) for two-port microwave components. The IMTF replaces the impedance matrix response with a zero–pole–gain transfer function,… read more here.
