The caustic structure of the electromagnetic field is mathematically modeled, when it appears near the ground surface during the decimeter radio wave propagation in the ionospheric plasma. The caustic structures of the fields of the ordinary and extr

Using symbolic calculations, a method of local asymptotics is developed, which describes the diffraction focusing of electromagnetic and acoustic fields for edge and corner catastrophes. Explicit expressions are found for the unfolding coefficients,

The caustic and ray structures formed during propagation of electromagnetic waves in a plasma layer are studied in the case when the effective permittivity of the propagation medium linearly decreases as the altitude grows. The main attention is focu
