let me start with saying I've missed a few lectures so im learning this online.

http://en.wikipedia.org/wiki/Magnetic_field

First part under 'Maxwell's equations' section
V being the triangle thing, which i take to mean d/dx+d/dy+d/dz

Which gives you a result in the i direction, nothing in j,k (y,z).

Honestly ive never seen Z before, do you mind showing me the equations you used ?

C)
This is just the cross product of the perpendicular electric and magnetic fields and is correct ?

http://en.wikipedia.org/wiki/Impedance_of_free_space
Section plane wave solution. We have time continuous fields. That simplify maxwells equations a lot.

ad c) Yes but consider peak value and rms value. It depends what you have, then you have to add 1/2 or not.

Do you have a solution somewhere???

Second part let me take a look into my cryst... eeeeh books Grin
