A theoretical and computer Investigation is made of the Influence of spatial and dynamic heterogeneity in the distribution of nonequilibrium conductivity in a semiconducting plate on the response in a SHF-displacement circuit. It is shown that spatial heterogeneity of the distribution leads to deterioration in conversion efficiency of the signal from the optical to the SHF range, and dynamic heterogeneity to increase in inertia of the.SHF circuit with a semiconducting sample. A relation is obtained allowing the thickness of the semiconductor sample at which there is no-heterogeneity of the distribution of either type to be determined.
