“…Semi-analytical full-wave transmission line (TL) models are proposed in literature to catch high-frequency effects like dispersion related to finite size [17][18][19] or losses associated to spurious radiation [20,21]. In this paper we use a generalized TL model, derived from the EFIE formulation presented in 2.1.…”

“…The main difference between the classical TL model and the ETL one is the non-local relations imposed by (8) and (9). If k is the wavenumber and t the characteristic transverse dimension of the interconnect, the classical TL model is valid for , (typically for kt up to 0.1), whereas the ETL model may be used up to [17][18][19][20]. The computational cost of this model is given by the cost of a TL model, augmented by the cost of integrals (8) and (9), which is strongly affected by the cost of the GFs evaluation.…”

Integral formulations are widely used for full-wave analysis of microstrip interconnects. A weak point of these formulations is the inclusion of the proper planar-layered Green's Functions (GFs), because of their computational cost. To overcome this problem, usually the GFs are decomposed into a quasi-dynamic term and a dynamic one. Under suitable approximations, the first may be given in closed form, whereas the second is approximated. Starting from a general criterion for this decomposition, in this paper we derive some simple criteria for using the closed-form quasi-dynamic GFs instead of the complete GFs, with reference to the problem of evaluating the full-wave current distribution along microstrips. These criteria are based on simple relations between frequency, line length, dielectric thickness and permittivity. The layered GFs have been embedded into a full-wave transmission line model and the results are first benchmarked with respect to a full-wave numerical 3D tool, then used to assess the proposed criteria.

“…The starting point is the Enhanced Transmission Line (ETL) model [14][15][16][17], which provides the full wave current distribution in the frequency ranges of interest. This model has been presented in [14] and [16] for coupled microstrip with homogeneous dielectrics. A first attempt to extend the model to inhomogeneous dieletrics is given in [17].…”

Abstract-The paper deals with the evaluation of the far-field radiated emissions from high-speed interconnects when the frequencies are such that the distribution of the currents along the traces is no longer of TEM-type. Instead of a computationally expensive numerical full-wave model, here a generalized transmission line model is used to obtain the current distributions. This full-wave transmission line model is derived from an integral formulation and is here extended to include in efficient way the layered media Green's Functions. The proposed tool is successfully benchmarked to references given in literature and case-studies of practical interest are carried out, referring to a coupled microstrip, driven either by differential and common mode currents. This analysis highlights the existence of a transition range where the error made by evaluating the emission using the classical transmission line current distribution is still negligible. Here a rule of thumb is derived which provides a simple criterion to estimate this extension of the range of validity of the classical transmission line.
