Description

The experiment P3.7.4.6 investigates total reflection of microwaves at media with lower refractive indices. We know from wave mechanics that the reflected wave penetrates about three to four wavelengths deep into the medium with the lower refractive index, before traveling along the boundary surface in the form of surface waves. This is verified in an experiment by placing an absorber (e.g. a hand) on the side of the medium with the lower refractive index close to the boundary surface and observing the decrease in the reflected intensity.
