Analysis of transmission-line equation based on LOD-FDTD

The derivatives in the transmission-line equation can be approximated by difference formula which must satisfy CFL condition. LOD-FDTD provides an unconditional stability method to get the updating equation by alternately solving for the implicit and explicit equation, which improves the computational efficiency greatly, and saves computer resources and memory. In this paper, simulation results demonstrate the exactness and stability of the engineering LOD-FDTD in transmission-line equation.
