摘要:

A wider‐angle parabolic wave equation (PE) previously obtained by factorization of the Helmholtz equation and interpretation of the square‐root operator is derived by another method. The wider‐angle capabilities of this PE are compared with the standard PE, using an analytically tractable case. The problem of using a PE in the nearfield is discussed.
