WKBZ: Adiabatic Mode Program Version 1.1 Introduction WKBZ [ 1-2 ] is very effective for solving acoustic propagation problems. Version 1.1 is designed to calculate transmission loss in range_dependent deep ocean. In this version, the sound field is computed from the contributions of those modes trapped in water column.
