Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I need to solve the following trigonometric equation. Some time ago I would have used Fortran with the appropriate libraries but now I was wondering whether there is any better approach. Any suggestion?

w^2/c^2= k//^2 - Sqrt(w^2 Eps_b^2/c^2 - k//^2) * Tan[Sqrt(w^2 Eps_b^2/c^2 - k//^2) * d/2]

where:

c= speed of light in vacuum

k//= variable

d= parameter

w= frequency

Eps_b= parameter

I need to plot w(k//) keeping in mind that "c", "d" and "Eps_b" are just parameters.

Cheers
