Abstract

In this paper, a novel method using conformal technique of finite-difference method (FDM) is proposed to capacitance extraction of microstrip lines. Instead of deriving the average dielectric constant epsilon, this method uses electric field numerical weights to process the inhomogeneous cells, and takes the discontinuous effects of both inhomogeneous Ampere cell and Faraday cell into account. Besides, a new boundary condition is proposed, where the cells obeying exponential distribution are added at boundary. The new method shows good agreement with the measurement and traditional methods.
