| Abstract: | The nonlinear behavior of acoustic and electromagnetic impulses in structurally heterogeneous and heterophase media is considered.
The example of a signal amplitude spectrum shift to the low-frequencies is studied. The laboratory results of ultrasonic measurements
and georadar field data are presented. |
