##### Reference no: EM13247298

An x-y plane separates two materials. Material 1 covers z < 0, while material 2 covers the z > 0 region. There is no surface current or charge on the boundary between the two materials.
Material 1 has a uniform electric field of E = x-hat + 2y-hat + 3z-hat V/m, and a uniform magnetic field of H = x-hat +2y-hat + 3z-hat A/m.

What are the electric and magentic fields in Materical 2, right at the boundary?
