Quasiclassical theory has been used to study the Josephson effect for the junction consisting of high-{ital T}{sub {ital c}} superconductor, insulator layer, and high-{ital T}{sub {ital c}} superconductor. Our result shows that for the {ital d}-wave pairing state and certain crystal orientations of the two superconductors, the current phase relation has the form {ital I}({phi})={ital I}{sub {ital c}}sin(2{phi}). Thus, the main Shapino step and Fraunhof diffraction pattern have the forms {ital V}={ital h}{nu}/4{ital e} and {ital I}{sub max}({Phi})={ital I}{sub {ital c}}{vert_bar}sin(2{pi}{Phi}/{Phi}{sub 0})/(2{pi}{Phi}/{Phi}{sub 0}){vert_bar}, respectively. We have compared our result with those of other types of Josephson junctions and discussed the implication of this property in identifying the pairing state symmetry of the high-{ital T}{sub {ital c}} superconductors.
