Radiation modeling of terahertz transmission-line metamaterials

Philip W. C. Hon; Amir A. Tavallaee; Zhijun Liu; Benjamin S. Williams; Tatsuo Itoh 2012 Conference on Lasers and Electro-Optics (CLEO), 2012

The cavity antenna model is applied to terahertz passive transmission-line metamaterials based upon metal-insulator-metal waveguides to predict their far-field radiation polarization. The model is verified experimentally by angle-resolved reflectivity spectroscopy of a planar composite right/left- handed metamaterial transmission-line array, which also allows for mapping of the waveguide dispersion.

A transmission line method to compute far-field radiation by arbitrarily directed Hertzian dipoles in a 1-D EBG structure

Xuan Hui Wu; A. A. Kishk; A. W. Glisson 2006 IEEE Antennas and Propagation Society International Symposium, 2006

In this paper, a transmission line method is developed to compute the far- field radiation of arbitrarily directed Hertzian dipoles that are embedded in a 1-D EBG of multilayer slabs. Based on the reciprocity theorem, the evaluation of the far-field is transformed into the evaluation of the field in the 1-D EBG structure due to an incident plane wave. The ...

Guiding and radiating properties of a metamaterial-based Resonant-Slot coupled cavity chain

H. Kumric; W. Kasparek; S. Hrabar; D. Zaluski 2009 34th International Conference on Infrared, Millimeter, and Terahertz Waves, 2009

Application of the resonant-slot coupled cavity chain as a Composite Right- handed-Left-handed transmission line (CRLH line) at microwave wavelengths is discussed. Design strategies for both the CRLH guiding structure and the backward-forward scanning leaky-wave antenna are reported. First theoretical valuations point to high power ability of such type of antenna, consisting of slotted waveguide with resonator-based filling. Applications in experimental ...

Time-domain reflectometry using arbitrary incident waveforms

Te-Wen Pan; Ching-Wen Hsue; Jhin-Fang Huang IEEE Transactions on Microwave Theory and Techniques, 2002

A novel time-domain reflectometry technique is developed for detecting the physical structures of transmission lines by using arbitrary waveforms. By discretizing both incident and reflected waves, we formulate the reflection coefficient of a nonuniform transmission line as a polynomial ratio in the Z-transform, wherein the numerator and denominator represent the reflected and incident waves, respectively. A reconstruction scheme is derived ...

Moment method solution based on impulse type expansion functions defined in infinite domain

Z. Ibragimov; H. Matzner; M. Haridim Microwaves, Communications, Antennas and Electronic Systems, 2008. COMCAS 2008. IEEE International Conference on, 2008

The well known paired-strips transmission line is solved by the method of moments (MoM) where the expansion functions are defined in infinite domain. The expansion functions obey the physical behavior near the edges of the line and at infinity, and based on impulse functions. We compare our solution to known solution based on conformal mapping and to other efficient MoM ...

Development of islanding early warning mechanism for power systems

Power Engineering Society Summer Meeting, 2000. IEEE, 2000

This paper discusses a computer algorithm which can be used to detect the conditions that will separate the power system into two or more islands. In order to provide an early warning mechanism for the dispatchers in the control center such that some actions can be taken before an islanding condition occurs, the proposed algorithm converts the power system topology ...

Microwave Performance of Undercut Active Region for Traveling Wave Electroabsorption Modulator

Lasers and Electro-Optics, 2005. CLEO/Pacific Rim 2005. Pacific Rim Conference on, 2005

A method based on undercut-etching-active-region is proposed to enhance the high-speed performance of the traveling wave electroabsorption modulator. It is found that increasing the widths of p-and n-cladding layer with the same i-layer to reduce the resistances in p-i-n waveguide can improve the microwave propagation loss and thus the high-speed electrooptical response.

Investigation of signal quality and radiated emission of microstrip line on imperfect ground plane: FDTD analysis and measurement

Electromagnetic Compatibility, 2001. EMC. 2001 IEEE International Symposium on, 2001

Taking four kinds of imperfect ground planes as examples, the effect of the imperfect ground plane on the signal integrity (SI) and electromagnetic interference (EMI) for high-speed digital transmission line on the printed circuit boards (PCB) are investigated both by FDTD simulation and experimental measurement. It is found that good signal quality does not guarantee good EMI performance and ill ...

Transmission Lines as Frequency Modulators

Radio Engineers, Proceedings of the Institute of, 1934

A method of producing frequency modulation is described wherein an eighth-wave radio-frequency transmission line is used as a modulation device. One end of the transmission line serves as a part of the tank circuit of the oscillator while at the other end is placed a variable resistance, such as a vacuum tube. Absolute linearity may be obtained with negligible amplitude ...

  • 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.

    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.
