   Hi Dr. Treeby and Dr. Cox,

   I am new to k-wave and I have a question about the wavenumber defined in kgrid. I am watching the k-wave user manual and it says that k = 2πf /c0. I am wondering shouldn't it be k = 2πf /c, and then c = c0/sqrt(εr * μr) ? (εr is relative permittivity, and μr is relative permeability.)

   I am asking this because I have got a list of data about a medium's relative permittivity, and I don't know how to apply them. I was thinking maybe I could change the wavenumber using the relative permittivity. That's where I came up with this question and got stuck.

   Thank you!

   Hi again,

   I thought about this question, and it seemed like that I have confused acoustic waves with electromagnetic waves, sorry to bother with this question.

   Thank you!
