in the dispersion relation of the surface plasmon(adsbygoogle = window.adsbygoogle || []).push({});

the wavelength is proportional to square root of n. according to equation 5 in this paper:

https://newton.ex.ac.uk/research/emag/pubs/pdf/Barnes_JOA_2006.pdf

if n goes to infinity, then what will be the value of wavelength.

Thank you
