Dispersion in coupled transmission lines
Proceedings of the IEEE, 1980Propagation of time harmonic waves in a system of coupled transmission lines with losses is being considered. Such a system is usually dispersive. In a special case, a condition for dispersionless propagation is derived, which is a generalization of the known condition for uncoupled lossy lines.

Electromagnetic Coupling to Transmission Lines
Electromagnetics, 1988Abstract Three aspects of the problem of electromagnetic interaction with transmission lines are reviewed. The various source terms appearing in the transmission line equations are discussed, including the coupling of common to differential mode. The interaction of an electromagnetic pulse with above-ground multi-conductor power lines is treated ...

Reexamination of Josephson junctions coupled to transmission lines
Physical Review E, 2008The effect of dissipation when due to the load of a transmission line coupled to a Josephson junction is reconsidered and evaluated by means of a simple direct procedure that supplies analytical expressions. The results are in good agreement with the ones previously reported in the literature.

On the Transmission-Line Approach for the Evaluation of LEMP Coupling to Multiconductor Lines
IEEE Transactions on Power Delivery, 2015This paper provides some clarification on the subject of the response of multiconductor lines to lightning-originated electromagnetic fields. Specifically, the effect of the presence of more conductors on the line response is analyzed with and without taking into account the ground losses in the surge propagation.

IEEE transactions on microwave theory and techniques, 2020
In this article, a Schottky diode-based microwave rectifier that employs coupled transmission lines (CTLs) is proposed. CTL is herein used to enhance the voltage amplitude across the Schottky diode with the consequent increase in the rectifier efficiency,

Coupling between microstrip transmission lines
1995 International Conference on Electromagnetic Interference and Compatibility (INCEMIC), 2002The finite difference time domain (FDTD) method is applied to predict the coupling between coplanar microstrip transmission lines. Calculated values of coupling coefficients are found to be in good agreement with the measured data.

IEEE Microwave and Wireless Components Letters, 2019
A compact fifth-order wideband bandpass filter (BPF) using simple coupled lines with sharp rolloff skirts is proposed in this letter. Five transmission poles within the passband and eight deep transmission zeros from 0 to $2\!f_{0}$ ( $f_{0}$ denotes ...

Josephson Transmission Lines Coupling
1991The problem of the matching of a Josephson transmission line (JTL) to external loads presents noticeable difficulties because of the complexity of the nonlinear wave-propagation that takes place in this spatially distributed structure. In a continuum-limit approximation, the equation for a JTL is a sine-Gordon equation containing loss and forcing terms

Field-to-transmission line coupling models
2020This chapter presents the coupling of lightning electromagnetic fields to overhead and underground lines based on the transmission line approximation. The chapter starts with an introductory section in which the advantages and the drawbacks of three approaches, namely the quasi-static approach, the transmission line approach, and the antenna approach ...

The Importance of Losses in Transmission Lines Coupling
The Sixteenth Conference of Electrical and Electronics Engineers in Israel,, 2005The problem of coupling between transmission lines is fundamental in electromagnetic compatibility, and it has therefore been given much attention. In the models (whether lumped or distributed) generally used to solve this problem the losses have been neglected.
