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

Novel acceleration approaches of accurate and efficient modeling of high speed interconnects in layered media

“…Two different fast convergent sine cosine series, also known as two fast convergent series (FCS), are used to accelerate the summation of the leading term after the asymptotic extraction to the Green's functions and the basis functions in the spectral domain [35]. And, it has been extended to handle the shielded microstrip with multiple metal lines in the same layer over a layered substrate [74]. However, the higher order asymptotic approximation need lots of work to find the leading term coefficients, and it inevitably bring in errors due to asymptotic approximation of both the Green's function and the basis functions.…”
