Abstract :
A method for obtaining two-term asymptotic modal approximations is described. Propagating modes are treated for range-independent shallow waveguides with downward refracting sound speed profiles. The approximation formulas are convenient for displaying the variations resulting from changes in environmental and acoustic parameters. Estimates for the validity and accuracy regimes of the modal approximations are obtained.
