t_params = s2t(s_params)
t_params = s2t(s_params) converts the scattering parameters s_params into the chain scattering parameters t_params. The s_params input is a complex 2-by-2-by-m array, representing m 2-port S-parameters. t_params is a complex 2-by-2-by-m array, representing m 2-port T-parameters.
This function uses the following definition for T-parameters:
![]()
where:
a1 is the incident wave at the first port.
b1 is the reflected wave at the first port.
a2 is the incident wave at the second port.
b2 is the reflected wave at the second port.
