FIELD: physics.
SUBSTANCE: depressions are made on one boundary of contact in one of the matched media and said depressions are filled with material with defined acoustic impedance which is different from impedance of that medium, characterised by that the depressions have an arbitrary shape and dimensions, wherein the depth of each of the depressions at different points of its projection on the flat boundary of contact of the matched media is a variable.
EFFECT: wider field of use of the method of acoustic matching of elastic media with a flat boundary of contact.
