Hello everyone!
I want to solve the equation below,
where u is complex permeability; u=u'-ju''. e is complex permittiity; e=e'-je'', and ft/c is constant.
Here I want to find the value of u=u'-ju'' satisfying the above equation when the e=e'-je'' value is given.
As a novice I tried with code below, but it didn't work.
if true
% code
endsyms e u;
e=10-4.6*1i;
ft=24;
c=299792458000;
F = sqrt((u)/e)*tanh((1i*2*pi*ft/c)*sqrt((u)*e))-1;
Can anyone help please?
Thank you for your reply in advance.

>> syms u
>> e=10-4.6i;
>> ft=24;
>> c=299792458000;
>> F = sqrt((u)/e)*tanh((i*2*pi*ft/c)*sqrt(u*e)) == 1;
>> solve(F,u)
Hope this helps.
