This paper deals with the propagation of millimeter wave through the layers of dielectric bodies. In order to obtain the expression for power loss each layer has been assumed as a dielectric wave guide tied with dielectric particles. Using the concept of electromagnetic wave propagation through a wave guide the expression for dielectric loss has been obtained. It has been found that the dielectric loss increases with increasing frequency and decreases with increasing visibility. It has been also found that the dielectric loss of the incident energy dependence heavily on particle size for different frequencies and visibility. In the lower range of the frequency the dielectric loss dominates over other losses, however at the higher range of the frequency the absorption loss has got its minimum value.
