In the paper, the possibility of surface transversal waves existence on an elastic surface layer with artificially induced periodic inhomogeneities has been described. Such kind of waves, unlike well-known surface modes sustained close to the surface boundary by an elastic layer as wellas constant or periodic electrical short, have potential to transfer higher energy with higher velocity. Such parameters are very important for applications of sensors. In the work, some outline of the theory, chosen qualitative aspects of such wave propagation on regular crystal surfaces as well as the resultsof preliminary experimental tests were presented.
