Microwave Thickness Measurement of Lossy Layered Dielectric Slabs using Incoherent Reflectivity
Radiative transfer theory is used to calculate the incoherent effective reflectivity (Γe) for a multilayer lossy dielectric medium backed by a conducting plate. The theoretical results of this formulation are compared with that of the coherent approach. Several test cases are presented to show the characteristics of Γe as a function of thickness, and dielectric constant of the dielectric layers, and frequency. The results can ultimately be used in nondestructive dielectric thickness measurement.
