Abstract
A structure for compressing an acoustic surface wave into a symmetric higher energy density output surface acoustic wave. Conductive strips are placed in parallel upon a piezoelectric surface. When a symmetric input is generated at one side of the multistrip coupler, the energy of the input wave is compressed into the center channel and is presented at the output in a single moded symmetric form.
