# Dispersion relation of a transmission line - questions

Hi,

I have transmission line with dispersion relation ω=sin(kx), so then means that for one value of ω I have two values of k. I apply voltage with some frequency with is allowed to move in the line. First question is, how can I influence what k will be generated inside the line. The another question is, if there is somehow possible to generate a wave not with generating frequency ω like in the first example but to generate wavelength, basically k.

Thank you

The only way to change k without changing the line construction is to vary ω.

and I see from dispersion formula that each ω has two k, so what key will be inside the line, and how can I switch is for another one.

Are you using a lumped-element model (discrete L's and C's) for the transmission line?

Yes
