### Transmission line max power transfer

I'm studying transmission lines and came up with the question why (voltage) reflection coefficient being zero is not equal to maximum power transfer (conjugate matching). I did some search and found ...

### Will the reflection from the load end of a transmission line affect the behaviour of an ideal voltage source?

Consider a transmission line with characteristic impedance of Z₀ and electrical length of λ/4. One end of the transmission line is terminated in a load of impedance (lets assume) 2Z₀. The other end is ...
