In this paper, a review of the low-rank factorization method is presented, with emphasis on
their application to multiscale problems. Low-rank matrix factorization methods exploit the …

Deep-learning (DL)-equipped iterators are developed to accelerate the iterative solution of
electromagnetic scattering problems. In proposed iterators, DL blocks consisting of U-nets …

We propose a wideband fast kernel-independent modeling of large multiscale structures; we
employ a nested equivalent source approximation (NESA) to compress the dense system …

We propose a mixed “skeleton” and “equivalence” nested approximation method to
compress the impedance matrix of the method of moments for the wideband multiscale …

In practice, the detailed geometry information of an off-the-shelf antenna is unavailable. To
achieve the estimation of radio frequency interference to an airborne patch antenna with …

This paper describes the approach developed to model the current return networks installed
aboard aircrafts having parts made in composite materials. The surface partial element …

Equivalent models of antennas are useful for the fast simulation of vehicle-to-everything
(V2X) communication. The existing antenna-equivalent models are inflexible because they …

The inherent difficulties of traditional preconditioning techniques are revealed by
numerically analyzing characteristics of method of moments systems with respect to …

A nested equivalence source approximation (NESA) of the electric field integral equation
with adaptive octree is explored for multiscale problems in this paper. The NESA low rank …
