Wave interaction produced in the lower night-time E region by extraordinary gyro-waves was studied for powers up to 500 kW into a circularly polarized array of 40 dipoles. Accurate values of the energy loss coefficient, the electron relaxation time and the electron collision frequency at heights of 85 km in the mesopause and 69 km in the D region were obtained. The electron density profile at the base of the night-time E region was deduced from the variation of the time constant of impressed modulation with frequency of the disturbing wave and is found to be stratified when the analysis is made using the Sen and Wyller M.I. theory. Wave interaction records for the daytime D region were obtained with continuous variation of the transmission ...
