In the past, model order reduction techniques have been successfully employed for 3-D PEEC interconnect models. This paper explores the diiculties in generating low order models when PEEC-like models include volume laments to accurately capture skin and proximity eeects.

in this study, focuses on applying the hp-version for forward modeling. the eit forward solver is normally based on the conventional finite element method (hfem). in h-fem, the polynomial order p of the element shape functions is constant and the element size h, is decreased. to accurately simulate the forward solution with the hfem, a mesh with large number of nodes and elements is usually need...

In this paper we present a unified framework for constructing spectrally equivalent low-order-refined discretizations the high-order finite element de Rham complex. This theory covers diffusion problems in $H^1$, $H({\rm curl})$, and div})$, is based on combining low-order discretization posed refined mesh with basis N\'ed\'elec Raviart-Thomas elements that makes use of concept polynomial histo...
