1. The problem statement, all variables and given/known data
In modelling the transmission line, usually we use R1L1G1C1. But if considering the ground plane, yet another set of R2L2 will appear. How to construct the 6 parameter of transmission line model?

2. Relevant equations
$$\gamma^2=(R+j\omega L)(G+j\omega C)$$
