Modal Cross Power in Quasi-TEM Transmission Lines
نویسنده
چکیده
This paper examines modal cross power in electromagnetic transmission lines. It shows that the cross powers of nearly degenerate modes may be large in quasi-TEM multiconductor transmission lines typical of modern electronic circuits at moderate and low microwave frequencies. The paper develops simple expressions to estimate the magnitude of these cross powers from the “power-normalized” conductor impedance and admittance matrices of the lines.

Spice Compatible Model for Multiple Coupled Nonuniform Transmission Lines Application in Transient Analysis of VLSI Circuits
An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...

متن کاملAccurate Quasi - Static Modeling of Microstrip Lines Over Lossy Substrates
A highly accurate, analytic quasi-static model of a microstrip over a semiconductor layer has been developed. The model agrees with full-wave calculations in all three modes of propagation (skin-effect, slow wave, and dielectric quasi-TEM), for both the attenuation constant α and the propagation constant β over a very wide range of dimension, substrate conductivity, and frequency. To achieve th...
