  • Abstract
    A conformal mapping based analytic formula is proposed for computation of the frequency dependent effective dielectric constant, εeff, of coplanar waveguides (CPW). This formula is correct in a wide frequency band and for wide range of CPW parameters, and models both negative and positive slopes in the frequency dependence of εeff. The results are especially useful for modeling microwave/millimetrewave and ultrahigh speed digital interconnects
