 P: 3,883 The diagram of the parallel plate transmission line is a more detail drawing from Field and Wave Electromagnetics by David Cheng. The charge is from boundary condition $\nabla \cdot \vec D = \rho_v$ and surface current from $\nabla X\vec H=\vec J$. But when comes to current derivation, the book only use the J component, there is no mention the contribution of the ρ from the E!!! How is the ρ plays in the transmission line that transform from EM wave to V and I?
