Nonlinear coupled TE-TM waves in Goubau line

2016 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2016
Nonlinear coupled electromagnetic TE-TM wave propagation in the Goubau line (a conducting cylinder covered by a concentric dielectric layer) filled with nonlinear inhomogeneous medium is considered. Nonlinearity inside the GL is described by the Kerr law.

Properties of microwave discharge in Goubau transmission line

2007 Joint 32nd International Conference on Infrared and Millimeter Waves and the 15th International Conference on Terahertz Electronics, 2007
Experimental results of microwave discharge excitation at the edge of single transmission line are presented. The device, which consists of a waveguide, a resonator and coaxial line for energy transmission to Goubau line, is described. The dynamics of plasma formation at the line edge is analyzed by photographic method.

Corrugated Goubau Lines to Slow Down and Confine THz Waves

IEEE Transactions on Terahertz Science and Technology, 2012
Corrugations on planar Goubau lines are presented in order to slow down and focus electromagnetic waves. A propagation effective index shift is observed between corrugated and non-corrugated planar Goubau lines. Influence of the corrugation geometrical parameters is studied.

Propagation of terahertz pulses along planar Goubau lines

2006 Joint 31st International Conference on Infrared Millimeter Waves and 14th International Conference on Teraherz Electronics, 2006
We present measurements and electromagnetic simulations of planar Goubau lines (PGL) on quartz substrate up to 1 THz. PGLs are single strip transmission lines. A very high-efficiency planar transition between a standard coplanar waveguide (CPW) and PGL is demonstrated A time-domain electroabsorption sampling method is used to measure the reflected and ...

Numerical Study of Multilayer Nonlinear Inhomogeneous Goubau Lines

2018 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2018
We consider propagation of surface TE waves in a circular metal-dielectric waveguide filled with nonlinear (Kerr nonlinearity) multilayered inhomogeneous medium. Analysis is reduced to solving a nonlinear transmission eigenvalue problem for an ordinary differential equation; eigenvalues of the problem correspond to propagation constants of the ...

Application of Goubau lines for millimetre and submillimetre wave gas sensors

IEE Proceedings - Microwaves, Antennas and Propagation, 2005
A study on the feasibility of the application of a Goubau line for millimetre and submillimetre wave sensors is presented. Simulations and calculations are performed for different line dimensions. Sensitivity of gas detection is examined in detail. Coupling effects between Goubau lines are also studied.

Metamaterial-Inspired Bandpass Filters for Terahertz Surface Waves on Goubau Lines

IEEE Transactions on Terahertz Science and Technology, 2013
This paper is focused on the application of split ring resonators (SRRs) to the design of compact bandpass filters for terahertz surface waves on single-wire waveguides, the so-called planar Goubau lines (PGLs). Through equivalent circuit models, electromagnetic simulations, and experiments, it is shown that, while a pair of SRRs coupled to a PGL ...

Studies in Overhead Wire--Goubau Line Above Ground

IEEE Transactions on Microwave Theory and Techniques, 1977
The transition theory which Kikuchi proposed first was improved and expanded in the range of the Sommerfeld line above ground and even the Goubau line (G line) above ground. Then it was proved by the experiment with the aid of the G line. The solution for the electromagnetic field produced by an overhead wire is derived using Maxwell's equations and ...

An updated applied formulation for the Goubau transmission line

Journal of Applied Physics, 2019
The Goubau line is a unique transmission line that consists of only a single conductor. Its unique properties make it a solid candidate for low-loss RF propagation and wireless power transfer applications. However, the applied theory of this line that has been established thus far is missing key details of the line's characteristics.

Complex waves in a dielectric rod and goubau line

2017 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2017
Existence of complex TM and TE waves in a dielectric waveguide of circular cross section and a Goubau line is proved by analyzing functional properties of the dispersion equations (DEs) using the theory of functions of several complex variables and validating the existence of complex roots of DE. The method proceeds from the analysis of general setting
