An artificial boundary numerical method for the exterior problems of the hyperbolic equation is considered.Three kinds of equivalent exact nonreflecting boundary conditions are derived on a circular artificial boundary.Numerical examples are presented and effectiveness of these artificial boundary conditions is demonstrated.
