Conductor (wall) losses. A rectangular waveguide is made of aluminum, which has conductivity of 3.6 x 107 S/m. The walls of the waveguide are thick and the internal dimensions are a = 25.4 mm and b = 38.1 mm. Assuming the waveguide is empty (free space), calculate:
(a) The power loss per meter length in the TE01 mode at f'fc = 2. Assume the amplitude of the longitudinal magnetic field intensity is 1 Aim.
(b) The attenuation constant due to losses in the walls.
