Taking into account the inhomogeneity of the ion density and dust charging, the propagation of dust-ion acoustic solitary wave (DIASW) in a non-planar and inhomogeneous dusty plasmas is investigated analytically. The analytical expressions for the evolution of DIASW and the emitted radiation profiles of DIASW caused by the combined effects of non-planar geometry and inhomogeneity are obtained.
