Homework Statement
Given the Z component of E inside a rectangular wave guide, Find the ratio of the maximum charge density on the plane x = 0 to the maximum charge density on the plane y = 0.
Additionally, Find the ratio of the maximum surface current on the x = 0 plane to the maximum surface current on the y = 0 plane.
I don't need someone to work out the problem for me, i just need help with the general approach. I can be more specific with the exact electric field given if necessary.
Homework Equations
The Attempt at a Solution
since my z component of E is non zero, I know i must have a TM mode since rectangular wave guides do not support TEM mode waves.
therefore, my z component of B = 0, and i can then go ahead and calculate the different components of my electromagnetic fields from equations derived in my book.
At this point, i know what my E and B fields are inside the wave guide. My book also says we assume that wave guides are perfect conductors so that E=B=0 inside the walls and that free charges and currents will be induced onto the walls in order to maintain the boundary conditions at the inner wall that E parallel and B perpendicular must both be 0.
Do i try and use these boundary conditions to find out my charge and current densities?
