Behavior of structure function of refraction coefficients in different turbulent fields.

Deviations of experimental data on the effect of atmospheric turbulence on electromagnetic wave propagation from a standard Kolmogorov (or Obukhov-Kolmogorov) model are examined from the standpoint of the behavior of atmospheric passive scalar spectrum. It is pointed out that these deviations are not random and can be explained on the basis of today's ideas of passive scalar behavior in the atmosphere. This approach allows us to view electromagnetic radiation transfer in random media in a new way and to make the necessary steps for developing a generalized model of this phenomenon.

Changes in modulation transfer function and optical resolution in helical turbulent media.

We study the change in the behavior of the modulation transfer function and resolution with changing properties of a turbulent medium. It is shown that the form and the behavior of the functions under study undergo significant changes at the transition from Kolmogorov's to a helical type of turbulent medium. These changes should be taken into account in developing models of electromagnetic radiation propagation through a medium as well as in interpreting experimental data.
