Modified Transmission and Reflection Coefficients of Nonuniform Transmission Lines and Their Applications

IEEE Transactions on Microwave Theory and Techniques, 1998
By employing the ABCD transmission matrix of a transmission line, we formulate the reflection and transmission coefficients of a nonuniform line as polynomial ratios in Z-transforms. Such formulations reveal explicit relationships between transmission and reflection coefficients of a nonuniform line.

Reflection and Transmission Coefficients for Transition Layers

Studia Geophysica Et Geodaetica, 1974
Formulae are derived for the reflection and transmission coeficients of plane elastic waves for a transition layer. Haskell's technique and the so-called delta matrices[5, 7] are used for this purpose. No problems are encountered in deriving the reflections and transmission coefficients from Haskell's matrices[3].

Introduction of Reflection and Transmission Coefficients for Nonuniform Radiating Transmission Lines

IEEE Transactions on Electromagnetic Compatibility, 2015
In the framework of a high-frequency transmission-line theory for nonuniform lines (TLST), new reflection and transmission coefficients are derived using generalized definitions of equivalent quantities from the classical transmission-line theory. This leads to local and frequency-dependent reflection and transmission coefficients expressed in terms of

Reflection and Transmission Coefficients of a Periodic Dielectric Slab

Proceedings of the IEEE, 1978
The plane-wave reflection and transmission coefficients of a dielectric slab having a sinusoidal variation of its permittivity are deduced from the solution of the full electromagnetic boundary-value problem and compared with the results of the approximate procedure based on the coupled-mode equations for the slowly varying amplitudes.

Fresnel Reflection and Transmission Coefficients for Complex Media

2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2017
Fresnel reflection and transmission coefficients are well known for the two idealized cases when the two media are either perfect dielectrics [1] or one is a dielectric and the other is a perfect electric conductor (PEC) [2]. However, such is not the case when either one or both media have loss.

Reflection and Transmission Coefficients of Multiple Chiral Layers

Science in China Series E Engineering and Materials Science, 2006
This paper presents a general analysis of reflection and transmission coefficients of multiple chiral layers in detail. Reflection and transmission coefficients through multiple chiral layers are computed and presented particularly for the incident wave of parallel polarization for a number of cases―a wide range of incidence angle, neigh- boring center
