Use MATLAB to plot the attenuation for the TE₁₀ mode a of waveguide with copper walls as a function of frequency. Do this for frequencies above cutoff. Keep in mind that R_s varies with frequency. Take a = 2b = 1 cm, f_c=10 GHz, and assume that the waveguide is filled with a dielectric having ε_r = 2.25.
