A New Approach to Dispersion Analysis of Graded Index Optical Fibers

H. J. Carlin; H. Zmuda 1985 IEEE MTT-S International Microwave Symposium Digest, 1985

The dispersion characteristics of graded index optical fiber are studied using a transverse transmission line circuit representation. For round fibers new approximations have been developed which significantly simplifies the analysis. An interesting perspective as to the physical mechanisms underlying the dispersion characteristics of such fibers result from circuit theoretic considerations.


Analysis of cylindrical microstrip lines utilizing the finite difference time-domain method

T. Kitamura; T. Koshimae; M. Hira; S. Kurazono IEEE Transactions on Microwave Theory and Techniques, 1994

This paper presents full-wave analysis of the cylindrical striplines and the cylindrical microstrip lines utilizing the finite difference time-domain method in a circular-cylindrical coordinate system. Numerical results on the normalized characteristic impedance are in good agreement with the available results. Furthermore, the junctions of the coaxial transmission line and the cylindrical microstrip line are analyzed to show the usefulness of ...


On the dispersion in TLM and FDTD

M. Krumpholz; P. Russer IEEE Transactions on Microwave Theory and Techniques, 1994

The dispersion relations of a two-dimensional TLM mesh and a three-dimensional TLM mesh with condensed symmetric nodes are calculated. For the calculation of the TLM dispersion relations, we use a generalized method which can be applied to any TLM node described by square scattering and propagation matrices of equal dimension. Introducing the FDTD Hilbert space representation, it is shown that ...


Definition of the high frequency characteristic impedance of an overhead conductor

G. E. Bridges Electronics Letters, 1990

A theory for the high frequency characteristic impedances of a conductor located above a lossy earth is presented. In the past, studies of overhead power transmission lines have relied on Carson's circuit based theory to determine the characteristic impedances, this being a low frequency theory which may be inaccurate when studying high frequency applications.


Numerical conformal transformation of three-magnetic-wall structures

E. Costamagna IEEE Transactions on Microwave Theory and Techniques, 1989

Methods are presented to transform general two-conductor, three-magnetic-wall line structures into less complicated geometries using conformal transformations. These geometries can be solved or have been solved previously by numerical techniques

  • Metaline Antenna

    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.

  • The Uses of Electrostatics

    This chapter shows where actual use of electrostatic analysis is involved in actual structures. It begins with a section on basic circuit theory, because this is a discipline based on electrostatic (and magnetostatic) approximations whose use is implied in the functioning of the various structures. The chapter provides a brief introduction to transmission line theory that is presented in handbook format, with only the necessary equations, with no supporting derivations. Although vacuum tubes and cathode ray tubes have been phased out by solid-state devices, some electron beam devices, such as the scanning electron microscope (SEM), remain in use. A very high electric field can be obtained by the combination of a very sharp thin tip of metal and the use of high potentials.

  • Meta-Smith Charts and Their Applications

    This book presents the developments and potential applications of Meta-Smith 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, Meta-Smith 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.
