T. S. Pong; M. A. Brooke Proceedings of the 32nd Midwest Symposium on Circuits and Systems,, 1989
An algorithm for the extraction of circuit parasitics in integrated circuits using classic transmission line models are discussed. This gives a better account of the DC and AC characteristics of interconnects than models incorporating exclusively either the R or C components. A network reduction technique used to simplify the extracted RC network at userspecified accuracies to manageable complexities, especially for ...

Using ideal transmission line model, we find the optimized length for suppressing the periodicity in the frequency response in periodic structure. Optimized length is applied to photonic bandgap (PBG) microstrip structures and we show the existence of optimized etched hole size in ground plane for suppressing the periodicity in the frequency response in PBG microstrip structures and find them.
Technique for Reducing Transient Voltages in MulticonductorShielded Cables
Nelson Theethayi; Ziya Mazloom; Rajeev Thottappillil IEEE Transactions on Electromagnetic Compatibility, 2007
It is a common practice that the unused pairs (inactive conductors) in shielded cables are left open (open circuited at the terminal block) in telecommunication systems. In this paper, it is shown by both theory (based on transmission line analysis) and experiments that if those inactive conductors are shorted to the cable shield, then the transient voltages on the other ...

In this paper, the BaumLiuTesche (BLT) equation is extended from the frequency domain into the time domain, so as to permit an analysis of a transmission line with nonlinear loads at each end of the line. To do this, we use both the voltage and current BLT equations in the time domain, together with the nonlinear vi relationships for the ...

This chapter designs a line antenna where the beam scans seamlessly with change in frequency from the backward direction to the forward direction through the broadside direction. This line antenna is designated as a metamaterial¿¿? based line antenna or metaline and the design is performed using transmission line theory. The metaline shown in the chapter is designed as a beam¿¿?scanning antenna, where a broadside beam is obtained across a very narrow frequency region centered at the transition frequency fT. The amplitude of the excitation at each of the points F1 and F2 is the same, with an excitation phase difference of 180¿¿. This excitation provides constructive addition of the fields radiated from the two metalines at frequencies around fT. The backward inclined radiation occurs due to the fact that the current flows with a progressive phase constant toward the arm end T; in other words, the phase delays toward the feed point F.

This chapter presents aspects of transmission line theory that are beyond the techniques used to describe general two¿¿¿port networks using scattering parameters. The extension of scattering parameters to multiport networks is straightforward and the extension of ABCD parameters to multiport networks is limited practically to coupled transmission line networks. The chapter presents the transmission line theory required to change the reference plane of S parameters along the transmission line, and how to work with cascades when the characteristic impedance of the lines is complex. It presents an outline of microwave transmission line theory, including impedance matching using transmission lines. The chapter considers traveling waves on a transmission line with a possibly complex characteristic impedance. Concepts are presented that enable problems to be solved using S parameters with complex characteristic impedances.

This book presents the developments and potential applications of MetaSmith charts, which can be applied to practical and useful transmission line problems (e.g., metamaterial transmission lines and nonreciprocal transmission lines). These problems are beyond the capability of the standard Smith chart to be applied effectively. As any RF engineer is aware, a key property of the Smith chart is the insight it provides, even in very complex design processes. Like the Smith chart, MetaSmith charts provide a useful way of visualizing transmission line phenomena. They provide useful physical insight, and they can also assist in solving related problems effectively. This book can be used as a companion guide in studying Microwave Engineering for senior undergraduate students as well as for graduate students. It is also recommended for researchers in the RF community, especially those working with periodic transmission line structures and metamaterial transmission lines. Problems are also p ovided at the end of each chapter for readers to gain a better understanding of material presented in this book.
