The GEO Wavesource controls dispersion of acoustic energy using a
hyperboloid acoustical reflector in the “coupling plane”
(the vertical plane of a curved vertical tangent array) and a diffraction slot in the “non-coupling plane” (the horizontal plane of a
curved vertical tangent array). The patented Configurable Directivity Device consists of flanges that alter the diffraction s
lot’s
exit flare rate.
