The WKB theory for vector systems of integral equations is developed herein. A variational technique is used to derive the equations for the WKB amplitudes in x‐space or its dual k‐space. Compact, explicit solutions are obtained in one dimension. When a solution breaks down at a turning point, the dual‐space representation can be used to derive the connection formulas between WKB solutions. These connection formulas are equivalent to the rules of the Furry method. The Furry method is used to show how general golbal‐dispersion relations can be constructed.
