Measurement of specimen permittivity using a waveguide bridge

Soviet Physics Journal Aims and scope

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.
