研究目的
Investigating the existence and properties of symmetric surface complex waves in a Goubau line, a type of open metal-dielectric waveguide, and developing methods for their analysis and computation.
研究成果
The existence of symmetric surface complex waves in a Goubau line is proved, and methods for their analysis and computation are developed. The study provides a foundation for further research into wave propagation in open structures and inhomogeneous nonlinear media.
研究不足
The study focuses on symmetric surface complex waves in a Goubau line and does not cover all possible types of waves or waveguide configurations. The analysis is limited to the specific geometry and conditions described.
1：Experimental Design and Method Selection:
The study involves constructing perturbation of the spectrum of symmetric real waves with respect to the imaginary part of the permittivity of the dielectric cover. Closed-form iteration procedures for calculating the roots of the dispersion equation in the complex domain are developed.
2：Sample Selection and Data Sources:
The study focuses on a Goubau line, which is a perfectly conducting cylinder of circular cross-section covered by a concentric dielectric layer.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned in the paper.
4：Experimental Procedures and Operational Workflow:
Numerical modeling is performed using a parameter-differentiation method applied to the analytical and numerical solution of dispersion equations.
5：Data Analysis Methods:
The study involves the analysis of dispersion equations and the development of iteration procedures for calculating their roots.
