Maxwell's equations using vectors D and H

[blueyellow]

Homework Statement

Write Maxwell's equations for electromagnetism in differential form:

in matter, for a linear material, using the vectors D and H

The Attempt at a Solution

div D= ro (Gauss' law)
div H*mu*mu0=0 gauss' law in magnetism
curl (D/(epsilon*epsilon0))=-dB/dt(partial derivative) faraday's law
curl H=j(subscript f)+dD/dt (partial derivative) ampere-maxwell law

I wanted to check whether they were correct

That looks pretty close. You can check your answer here at hyperphysics:

BTW, if you want to write "epsilon*epsilon0", you should write "epsilonR*epsilon0", because epsilon = epsilonR*epsilon0. Or in LaTeX:

\epsilon = \epsilon_R * \epsilon_0

.

sorry, I just realized I don't know what epsilon r and mu r actually are. epsilon 0 and mu0 are the permittivity and permeability in free space aren't they? but what does the r stand for? I have tried looking this up
