The propagation properties of the Airy-Gaussian beams are introduced in a quadratic-index medium analytically and numerically. The linear momentum, the beam width, the beam center of the Airy-Gaussian beam are analyzed. The Airy-Gaussian beam shape and curvature repeats itself at intervals proportional to due to the potential barrier. The bend (the transversely acceleration) and the periodicity of the Airy-Gaussian beam depend on the parameters χ0 and azR.
