Finite element analysis for distribution of surface charge on current-carrying conductor

The purpose of this paper is to analyze distribution of surface charge density on DC-carrying conductor. A new numerical analysis method, based on finite element method, is proposed in this paper. Basically the method consists of two steps: first is to calculate inside field of conductor and second is to calculate outside field. Knowing the charge distribution on the conductor surface helps better understanding of the current in conductor and will be useful for extracting parasitic circuit parameters and modeling on-chip interconnects etc.
