In high dimensions, there are abundant coherent soliton excitations. From the variable separation approach of the celebrated Kadomtsev-Petviashvili(KP) equation and the coupled Burgers equation, several new multisoliton excitations are derived and some novel features or interesting behaviors of these structures are revealed.
