Simple Formula for the Wave Number of the Goubau Line
Electromagnetics, 2014For the first time, a non-iterative formula is derived for the wave number of the Goubau line with a small cross-section. This formula makes use of Lambert's W function. Its accuracy is assessed with the help of a few examples.

Application of Goubau lines for millimetre and submillimetre wave gas sensors
IET Microwaves Antennas and Propagation, 2005A 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.

Complex waves in the Goubau line
2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021The paper addresses a problem of the TE-wave propagation in the Goubau line. The propagation problem is reduced to a transmission eigenvalue problem for an ordinary differential equation. Spectral parameters of the problem are propagation constants of the waveguide.

2016 10th European Conference on Antennas and Propagation (EuCAP), 2016
We consider a homogeneous Goubau line (GL) with a lossy cover. We analyze the dispersion equation for symmetric waves with respect to the problem parameters, find radially symmetric complex waves, and examine their behavior. We show that longitudinal wavenumbers of complex waves are regular perturbations of the propagation constants of eigenwaves of ...

Cutoff Wavenumbers of Goubau Lines
IEEE Transactions on Microwave Theory and Techniques, 1979The cutoff wavenumbers k/sub nm/ of the surface wavemodes in a Goubau line are determined by a procedure that leads directly to the eigenvalue equation in the limit of zero values for the wavenumber of the infinite exterior medium. The same result has been obtained by a much longer procedure based on an extension of previous methods used in correction ...

Nonlinear TE-waves in nonhomogeneous Goubau Line
2021 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2021In this work, we study TE-polarized electromagnetic waves propagating in an inhomogeneous dielectric waveguide of circular cross section filled with a medium; the nonlinearity is simulated by Kerr’s law. For the numerical solution of the problem, an iterative algorithm is proposed, and its convergence is proved.

On the coaxial excitation of the modified Goubau line
Radio Science, 1980The problem of excitation of the modified Goubau line from a coaxial junction is analyzed using the Wiener‐Hopf technique and Fourier transforms in the axial direction. The analytical expressions reduce to those of Ledeboer in the absence of the air gap. The effects of the air gap in reducing the input reflection coefficient and in modifying such other

Microvawe Discharge Properties in Goubau Line
2007 International Kharkiv Symposium Physics and Engrg. of Millimeter and Sub-Millimeter Waves (MSMW), 2007In this paper, analysis from experimental results showed some regularity in microwave discharge behavior and in signal propagation along transmission line. Microwave discharge in thin (conductor diameter three times less then oscillator wave length) single conductor transmission line represents erosion discharge of torch type.
