yes,I know that this is EM wave frequency.but which EM wave? it is related to incident wave to plasma,or feeding frequency in surface wave plasma?

Hi. I have a problem. as you know,in a plasma medium(such as cylindrical tube),we have: εr = 1- [ ωp^2 / ω*(ω - jv) ] that : v = collision frequency ωp = plasma frequency but I don't know meaning of " ω " ,exactly. ω is RF feed frequency of plasma or incident wave frequency to plasma...
