I have a question concerning reflections due to impedance mismatching. Now, assuming a lossless TL, the latter is modelled by sections of lumped L-C segments where L in a series (sub)element of the transmission line and the capacitors connect to GND. I understand that this models the two wires of the TL and mathematically leads to the characteristic impedance Sqrt(L/C) used to calculate reflections once source and load impedances are also known.. Now to my question.. I know how to compute the reflection coefficient when source and load impedances are given. But how do i calculate the reflection introduced by a series capacitance in the TL, right between the source and the TL? (Or between TL and the load). I assume i have to include the series C into source or load, respectively...but how to deal then (for example) when there are two TLs in series and the series C is right between those?
Thanks a lot for explanations ;)
