Easy question for those who know, I expect. It would help me understand though.(adsbygoogle = window.adsbygoogle || []).push({});

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 thatdB/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 ;)
