Essay

The processes of propagation and scattering of sinusoidal wave in the homogeneous media with irregular boundary and pulse signal propagation in the locally non homogeneous domains with complex boundary. Determination of appearance conditions and obtaining of the correct numerical estimation of the well-known phenomena arising in the wave propagation in irregular two-dimensional structures. The problem of exitation of irregular two dimensional impedance wavegude by local source and by eigenmode of one of its regular parts, the problem of account of self-shadowing of the randomized step-like surface and the problem of restriction of the computation domain in the finite-difference method for two dimensional rectangular and three dimensional spherical virtual boundaries were solved strongly. Field of use is radiophysics.
