The longitudinal displacement of an elelctromagnetic beam upon reflection from a dielectric slab has been investigated. The experimental results, using 3 cm microwaves, are compared to those predicted by a theory based on a plane-wave approach. The experiment has been completed for both perpendicular and parallel polarization using a slab several wavelengths thick for angles of incidence around 45°. The agreement between experimental values and theoretical predictions is good.
