Question

A rectangular waveguide is depicted here. The waveguide is infinite along the y-direction. The four sidewalls are perfect electric conductors (PECs). Assume that both electric and magnetic fields exist in the region inside the waveguide. (a) Write the boundary conditions for the electric fields (both normal and tangential components) on the waveguide wall at xa. (15 points) (b) Write the boundary conditions for the magnetic fields (both normal and tangential components) on the waveguide wall at z 0. (15 points) al (c) The perfect magnetic conductor (PMC) is the magnetic analogue of the PEC. If the walls of this waveguide are PMCs, write the expression for the tangential magnetic fields at the Z x0 wall. (5 points)
