We investigate numerically that a finite Airy-Gaussian (AiG) beam varies itstrajectory and shape in the defected photonic lattices. The propagationproperties and beam self-bending are controlled with modulation depth andperiod of the photonic lattices, positive and negative defects, beamdistribution factor and nonlinearity change. For positive defects, thepseudo-period oscillation and localization of the AiG beam may be formed undera certain condition, while the beam is diffused for negative defects. Moreover,the solitons may appear during the propagation process when the self-focusingnonlinearity is introduced.
