Goubau Line Beam Instrumentation Testing, The Benefits

2014
At JLab and Bergoz Instrumentation Goubau lines are used for beam instrumentation testing. A Goubau line differs fundamentally from standard bench testing techniques in the way it produces the electromagnetic fields which interact with the DUT. This allows to acquire complementary information about DUT characteristics.

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.

A Reconfigurable Goubau-Line-Based Leaky Wave Antenna

2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018
A periodically-modulated leaky-wave antenna based on Goubau transmission line with an electronically steerable main beam is presented. Binary switches are connected between the conductive patches along the Goubau line antenna, allowing to vary the phase constant of the propagating wave and to make the antenna reconfigurable.

Characterization of the Goubau line for testing beam diagnostic instruments

Journal of Instrumentation, 2017
One of the main characteristics of the Goubau line is that it supports a low-loss, non-radiated surface wave guided by a dielectric-coated metal wire. The dominant mode of the surface wave along the Goubau line is a TM01 mode, which resembles the pattern of the electromagnetic fields induced in the metallic beam pipe when the charged particle beam ...

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 ...

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 ...

Research Results and Applications of Torch Discharge in the Goubau Line

IEEE Transactions on Plasma Science, 2011
The waveguide-coaxial microwave setup for an excitation of erosion torch discharge at the end of a single-conductor Goubau line in open air has been developed. Properties of erosion torch discharge and surface wave propagation in the Goubau line have been investigated.

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 ...
