Offdiagonal Sparameters, S12, S21, are referred to as transmission coefficients because they refer to what happens from one port to another. 28 Sparameters Larger works: A Network may have any number of ports. 29 Sparameters Larger works: A Network may have any number of ports. The Smatrix for an nport work contains n2 coefficients (Sparameters), each one representing a possible inputoutput path. 30 Sparameters Larger works: A Network may have any number of ports. The Smatrix for an nport work contains n2 coefficients (Sparameters), each one representing a possible inputoutput path. The number of rows and columns in an Sparameters matrix is equal to the number of ports. 31 Sparameters Larger works: A Network may have any number of ports. The Smatrix for an nport work contains n2 coefficients (Sparameters), each one representing a possible inputoutput path. The number of rows and columns in an Sparameters matrix is equal to the number of ports. For the Sparameter subscripts “ij”, “j” is the port that is excited (the input port) and “i” is the output port. 32 Sparameters Larger works: A Network may have any number of ports.
