Analytic and Numerically Efficient Scat- Tering Equations for an Infinitely Flanged Coaxial Line
نویسنده
چکیده
An infinitely flanged coaxial line is analytically solved with the mode-matching technique and Green’s function to propose a precise yet fast-convergent scattering solution for complex permittivity measurement. Based on virtual current cancelation, we formulate the open half-space fields in terms of coaxial modes and related Green’s functions and thus obtain the simultaneous equations with rapidly convergent integrals. Numerical computations were performed in terms of reflection coefficients and radiation patterns.

Determination of Electromagnetic Properties of Materials Using Flanged Open - Ended Coaxial Probe - Full - Wave Analysis
A full-wave analysis is applied to the scheme of measuring electromagnetic (EM) properties of materials over the frequency range of 0.3-4 GHz using a flanged open-ended coaxial probe. The excitation of complex waves, which include surface waves, radiative waves and radial guided waves in layered material media, is considered. With an accurate theory, this scheme may be used to measure both comp...

A solution is obtained for the problem of the propagation of electromagnetic waves in a semi-infinite flanged coaxial line with an infinite center conductor, in terms of an infinite set of coefficients which are determined by an infinite set of linear equations. The solution is discussed, in detail, in limiting cases which illustrate properties both of a thin vertical antenna on a plane perfect...

The existence of infinitely many solutions for an anisotropic discrete non-linear problem with variable exponent according to p(k)–Laplacian operator with Dirichlet boundary value condition, under appropriate behaviors of the non-linear term, is investigated. The technical approach is based on a local minimum theorem for differentiable functionals due to Ricceri. We point out a theorem as a spe...
