The main physical characteristic is that microwave waveguides are made out of conductive metals such as copper or silver. The dimensions of the cross section are tuned to the microwave frequency to be propagated. The cross section of the guide is usually rectangular with one dimension representing the H field (magnetic) and one dimension representing the E field (electric) of the electromagnetic wave. For rectangular waveguides, the frequency range that will propagate through the guide is
f_low = c/(2 * a) c = speed of light, a = cross sectional area
f_high = 2 * f_low
I have provided a site that has some pictures of waveguides.

The dimensions of the waveguide depend on the frequency of the microwave. The two dimensions are multiples of the wave length.

At a guess a sine wave?
