Abstract
A spectral model for refractive index fluctuations, showing the characteristic ‘bump’ at high wavenumbers, is proposed for theoretical studies involving optical propagation. Using this spectrum, analytical expressions are developed for the variance of log-amplitude that show good agreement with numerical results based on the Hill spectrum.Keywords
