Hi As we know, we have two kinds of Electromagnetic Boundary Conditions for interfaces in an electromagnetic problem.one is imposing the continuity of Bz and Hr and the other is applying the continuity of A(Magnetic Vector Potential) and the discontinuity of its derivative with respect to the...

Thanks dears I'm going to try these suggestions. Good luck :-)

Mathematica 6

It's something like this: Table[FindRoot[(a function of variable x containing Bessel functions==0),{x,k[[i]]}],{i,1,N}] I gave one starting point but I couldn't get the proper solution! I just want to know if there is another command for calculating these kind of equations or not? thanks a lot

Hi I have some problems in finding the proper starting value in FindRoot[] command. Cause I don't know exactly what the point is,I can't get the right answer! :cry: How can I find roots without having the starting point? Thanks
