Abstract
The proposed method for measuring the permittivity of the medium in the superhigh frequency band makes use of the depolarizing effect of the electromagnetic field. Upon exposing a dielectric particle to an electromagnetic field having a definitely oriented electric-field intensity vector, En, the reflected electric-field intensity vector, E0, will not, in general, coincide in direction with the incident field (as a result of depolarization). This depolarization depends upon the form and dimensions of the particle, on its permittivity, and on the wavelength.
