	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.
