If n is infinity, wavelength is equal to what?

    in the dispersion relation of the surface plasmon

    the wavelength is proportional to square root of n. according to equation 5 in this paper:
    if n goes to infinity, then what will be the value of wavelength.
    Thank you

    I don't see any n that could go to infinity in equation 5, and if you let one of the ε go to infinity (keeping the other constant) the square root has a finite limit.
