Under model conditions the influence of lateral waves of various types on the interference structure of near fields of a waveguide was investigated. The use of highly directed radiation produced by a parametric antenna allows us to selectively excite not only propagating modes of the waveguide, but also lateral modes produced by seismic (longitudinal and transverse) waves, propagating in an underlying ground.
