Efficient and accurate modeling of effective medium for interconnects in lossy shielded layered medium using fast convergent series

An approach for fast and accurate modeling of multiple interconnects in lossy shielded multilayered medium using the spectral domain approach has been presented. The acceleration in the evaluation of the elements of the MoM matrix has been achieved using asymptotic approximation of the Green´s function and the basis function followed by a quick approximation of the infinite series summation using a combination of two different types of fast convergent series (FCS). This approach is very versatile and can also be used to accelerate the spectral domain approach after inclusion of finite thickness and conductivity approximations. Also, it can be used to accelerate the spectral domain approach for multiple interconnects in different layers.
