I'm tryin' to get solutions from a system of 2 eqs involving Bessel functions (BesselJ/Y/K), related to the electromagnetic field in a coaxial fiber;
Something like (but much more complex!):
[2 k BesselK[0, b p3]*BesselY[1,b kc2](alfa+j beta)^2 + 4f^2[Pi]^2 [Mu]^2] / (BesselK[0, b p3]^2)
I use FindRoot but it can't find steady solutions (my variables are alfa and beta of "alfa+j*beta"). It always finds solutions but always different!
I know it's a difficult question, but I just need some suggestion to simplify the problem...
Thank you for the help
PS: In the attachment the 1st cell prepares the 2 equations, then there's my FindRoot and then two simplier versions of the 2 eqs (anyway without solution!)
