PCT No. PCT/DE88/00584 Sec. 371 Date May 9, 1990 Sec. 102(e) Date May 9, 1990 PCT Filed Sep. 19, 1988 PCT Pub. No. WO89/02675 PCT Pub. Date Mar. 23, 1989.A surface device with a conversion structure (12) mounted on the substrate (2) but outside the surface of the substrate provided for surface wave propagation. The conversion structure eliminates undesirable surfaces which occur.
