Application of Quasi-Tem Surface Impedance Approach to Calculate Inductance, Resistance and Conductor Losses of Multiconductor Microstrip Line System

Abstract

Abstract-In this paper a recent new quasi-TEM surface impedance approach has been applied to fast characterization of multiconductor microstrip lines in terms of inductance and resistance matrices and conductor losses. Application examples for frequency-dependent parameters of interconnect circuits with up to five conductors (three-, four-, and five-strips) have been reported. The propagation characteristics and attenuation of multimode symmetrical multiconductor system are obtained. The effectiveness of the applied approach is confirmed by comparison of the computed numerical results with those obtained by full-wave simulators. They are found to be in good agreement.

Calculating Radar Cross Section of Lossy Targets Using the Surface Impedance Approach

“…One of those methods is the technique proposed by [20], which has been improved recently in [15,16]. The main advantage of this technique is that it can be combined with a quasi-TEM approach to form the so-called quasi-TEM surface impedance approach.…”

“…To circumvent these constraints, Marqués et al have proposed an alternative approximated method making use of the surface impedance concept [20,21]. Recently, this concept has been improved in [15,16] by making use of a new calculation strategy.…”

“…The surface impedance technique used in this study has been developed in [15] for the calculation of conductor loss of single and two coupled rectangular microstrip lines. The accuracy of this technique has been improved recently in [16] for three, four and five coupled conducting strips embedded in a lossless dielectric medium. The main advantage of this technique, based on quasi-TEM approximations, is the simplicity to deal with rectangular resistive targets taking into account the thickness of the conductor and edge currents.…”
