Abstract:

The problem of wave propagation in a medium with fluctuating refractive index is considered, this problem being of interest from the standpoint of the theory of twinkling of stars and atmospheric acoustics. The problem is reduced to linearized equations satisfied by the phase and logarithmic amplitude of the propagating wave. Limiting cases are investigated and particular examples are considered to indicate the limits of validity of the geometric optics treatment and the nature of the corrections required to take account of diffraction effects.
