POLARIZATION, REFLECTION, AND ABSORPTION OF MICROWAVES
Electromagnetic waves consist of position-dependent and time-dependent electric and magnetic fields which are perpendicular to each other. These waves propagate in a direction perpendicular to both fields. In this experiment, we consider microwaves produced by a transmitter whose axis is vertical. The electric fields of these microwaves are therefore linearly polarized in the vertical plane and travel in the horizontal direction.
