Let the port‐2 be open‐circuited and an incident voltage is applied at the port‐1. The voltage wave reaches to the port‐2 and reflects from there. It reaches the port‐1 as the voltage wave . The maximum of the voltage wave occurs at the port‐2. The total port voltages are given below:

Thus, the [Z] parameters are obtained as follows:

The following [Z] matrix of a line section is obtained by keeping in view that the uniform transmission line is a symmetrical and reciprocal network:

For the lossless transmission line, γ = j β, α = 0 and [Z] is
