Rectangular Waveguide: Boundary Conditions for Electromagnetic Waves

[QUOTE="Observer Two, post: 4595138, member: 494353"] [h2]Homework Statement [/h2] I have a rectangular, hollow, conductor. Something like this: [ATTACH=full]165951[/ATTACH] The length in z direction should be infinite. The propagation of electromagnetic waves in the conductor are given via the equations: [h2]Homework Equations[/h2] [itex]\Delta \vec{E} = \frac{1}{c^2} \frac{\partial^2 \vec{E}}{\partial t^2}[/itex] [itex]\Delta \vec{B} = \frac{1}{c^2} \frac{\partial^2 \vec{B}}{\partial t^2}[/itex] Question 1: Which boundary conditions follow for the E field? And what does that mean for the B field? [h2]The Attempt at a Solution[/h2] Well. Since there are free charges in the conductor, the tangential component of the E field should be 0 (otherwise the charges would start to move). Which in return means the normal component of the B field must also be 0. Is there more I could derive from this or is that it? My answer seems a bit too simplistic ... [/QUOTE]
