It means that the conductor would behave as a super- +conductor and dielectric would be made of perfect dielectric medium. In a lossless +transmission line, power sent from a generating point would be equal to power re- +ceived at the load end.

As waves move towards the load end of the lossy transmission +line, distortion is caused by a change in speed. +The symbol for Single Lossy Transmission Lines(SLTL) is shown below- + +![ymod](https://user-images.githubusercontent.com/43288153/184139539-ed4eac77-934a-423c-8f7b-2cba4daf42d1.png) -- cgit
