Locally explicit time-domain radiationboundarycondition for 2-d and 3-d transient analyses of wave propagation in unbounded media were developed for the cylindrical and spherical wave equations.
Firstly according to radiation theory the boundary function of planar diffraction body is given, based on this condition the Kirchhoff diffraction formula is deduced and obtained.
