Solution:

Rectangular waveguides do not support TEM waves. wave having no axial component of E or H - If we assume the TEM wave exists within a hallow guide of any shape, the line of H will be a closed loop in a plane perpendicular to the axis (,ˉH)=0

Now according to Maxwell eq,

LHdL=3Jds+sˉD/tds

the conductor is hollow having no inner conductor the axial current is displacement current. (Conduction current is zero.).
