The RF Toolbox add-on to MATLAB [26] and several books (for example "Network scattering parameters" [27]) use this last definition, so caution is necessary. The "From S to T" and "From T to S" paragraphs in this article are based on the first definition. Adaptation to the second definition is trivial (interchanging T11 for T22, and T12 for T21 ...
The Zoeppritz equations consist of four equations with four unknowns [] = [ ] [ ]R P, R S, T P, and T S, are the reflected P, reflected S, transmitted P, and transmitted S-wave amplitude coefficients, respectively, =angle of incidence, =angle of the transmitted P-wave, =angle of reflected S-wave and =angle of the ...

In physics, the S-matrix or scattering matrix is a matrix that relates the initial state and the final state of a physical system undergoing a scattering process.It is used in quantum mechanics, scattering theory and quantum field theory (QFT).

S11, a postcode district in Sheffield, England S-11, a creature in the Sharktopus film Voltage reflection coefficient S 11 {\displaystyle S_{11}} of a two-port network
If you accept that the reflection coefficient is equivalent to the S11 scattering parameter of the load, and that Z0 is the impedance the load sees looking out of its port, i.e. the source impedance, then the formula as written contradicts the definition of S11 (see Scattering_parameters). S11 is defined as b1/a1; a1 is defined as (1/2) K1 (V1 ...
It is often preferable to work directly with these as they contain all the information that the full correlation functions contain since any disconnected diagram is merely a product of connected diagrams. By excluding other sets of diagrams one can define other correlation functions such as one-particle irreducible correlation functions.
