Refection/Transmission Coefficients at Media Interface and Lines Junction
ОглавлениеThe reflection and transmission coefficients of both the TE and TM‐polarized obliquely incident waves at the interface (x = 0) of physical media as taken as follow:
(5.2.24)
The reflection and transmission coefficients of TE‐polarized at the junction of two equivalent lines, shown in Fig (5.2b), are obtained from Ez‐field components of the incident, reflected, and transmitted waves using equations (5.2.2)–(5.2.4):
(5.2.25)
Thus, for the TE‐polarized obliquely incident EM‐wave, the line reflection, and transmission coefficients correspond to the reflection and transmission coefficients at the interface of two physical media. However, for the TM‐polarized case, shown in Fig (5.3b), change occurs for the transmission coefficient. The Ey‐field components of the incident, reflected, and transmitted waves using equations (5.2.12)–(5.2.14) are considered to define line junction reflection and transmission coefficients of the TM‐polarized case:
