Connection between the solution of the Helmholtz and parabolic equations for sound propagation
(NATO. SACLANTCEN, 1975/10)Using a conformal mapping technique in a rectangular waveguide, we present an exact integral relation between the solutions of the Helmholtz equation whose sound speed c(x,y) varies as a function of both depth y and range ...
