Easy question for those who know, I expect. It would help me understand though.
Generally, wherever I look for information the equation
curl E = - dB/dt
is given, but in some areas I see the equation
curl E(r,t) = j*omega*u0*H(r,t)
where j is the imaginary unit, omega is angular freq., u0 is permeability of free space.
B=u0*H so that's ok, but does this imply that dB/dt = -j*omega*B ?
Also, curl H(r,t) = -j*omega*e0*e*E(r,t) is given where e0 is permittivity of free space, e is a dielectric tensor. I assume this can be explained in the same way.
I'm missing a chunk of understanding as you probably notice ;)
