  2. Scattering parameters - Wikipedia

    en.wikipedia.org/wiki/Scattering_parameters

    The Scattering transfer parameters or T-parameters of a 2-port network are expressed by the T-parameter matrix and are closely related to the corresponding S-parameter matrix. However, unlike S parameters, there is no simple physical means to measure the T parameters in a system, sometimes referred to as Youla waves.

    Almost without exception, however, the scattering matrices implemented for RCWA are inefficient and do not follow long standing conventions in terms of how S11, S12, S21, and S22 are defined. [5] Other methods exist, like the enhanced transmittance matrices (ETM), R matrices, and H matrices.

    ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...

    S21 When using do not smoke. S22 Do not breathe dust. S23 Do not breathe gas/fumes/vapour/spray (appropriate wording to be specified by the manufacturer). S24 Avoid contact with skin. S25 Avoid contact with eyes. S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S27

    County Route S12 (CR S12), also known as Palomar Airport Road, San Marcos Boulevard, Twin Oaks Valley Road, and Deer Springs Road, is a county highway in San Diego County, California, United States. It runs through the North County region of San Diego County from Carlsbad Boulevard ( County Route S21 ) in Carlsbad to Interstate 15 near Hidden ...

    I suspect there is some confusion between the power S11 parameter and the voltage s11 parameter. I rederived the whole thing. If rho is the voltage transmission coefficient, then the scaled reflected power goes as rho^2, and the scaled transmitted power goes as (1-rho^2).
