"WebRecently, a new formulation called mixed boundary element method (BEM) was proposed for 3-D impedance extraction [5]. This method introduces an indirect boundary integral equation (BIE) to describe the electrical field in the inside domain of conductor, while using the direct BIE for the domain among conductors, as that in FastImp.
