a = 3.4 * 10^-6
lambda = 1.33 * 10^-6
n1 = 1.4675
n2 = 1.45
k0 = (2 * Pi)/lambda
U = a * sqrt[(k0*n1)^2 beta^2]
W = a * sqrt[beta^2 (k0*n2)^2]

U*BesselJ[1,U]/Bessel[0,U]=W*BesselK[1,W]/BesselK[0,W]

Using the value of a, lambda, n1, n2 I would like to find out the value of beta for which the above equation is valid. I tried to use FindRoot but I get a prompt nlnum. I have attached the in the file in which I have tried.

Please provide the required help.
