The reason why I have decided to start a new lecture series is explained in this article. The main purpose of transmission lines is to carry information using wave energy over long distances, which corresponds to the use of the telegrapher's equations in circuit theory. In this lecture, a new analysis method for the telegrapher's equations is explained. In other words, the equations are solved by the Laplace transform and expressed as the Riccati equation. The eigenvalue problem of the Riccati equation is solved to obtain a transmission equation and cascade matrix. It is suggested that the steady-state response can be obtained using the cascade matrix and may be applied to quantum theory.
