The diffraction of nonsinusoidal radio waves on natural media

The use of the nonsinusoidal electromagnetic waves in subsurface sensing is increasing more and more. The efficiency of their application is governed by a possibility to achieve a high resolving capacity in attenuation which is far less than that of radio pulses of similar duration. In some cases the analysis of diffraction phenomena can be performed in terms of the diffraction model for the lossless structures. As far as these structures are concerned we have derived compact analytical expressions describing the fields of the nonsinusoidal radio wave diffraction; the transient processes have been revealed and examined. Additionally, the limits of applicability of this model with various types of video pulses have been established
