Abstract

The present paper studies beyond-the-horizon propagation ot SEF in evaporation d.uct in presence or strong anisotropic fluctuations or the refractivity index. Errective technique to obtain numerically complex eigen values is suggested. On the base or this approach the modeling method. or SHF propagation in media with layer fluctuations o rerracti vity index is formed. Some examples or the influence oI'! fluctuations on beyond-the-horizon propagation are considers. A generalization or adia batic approximation ror opening systems with complex spectrum o eigen values and indefinite eigen runctions is suggested. Mechanism o exiting the evaporation duct by the high located SElF source is also discussed.
