The diverging and converging components of localized wave solutions are studied within the framework of both the Whittaker and Weyl plane wave expansions. The specific example of the splash pulse is considered because its evanescent components could be derived in an explicit closed form. It is shown that, in the Weyl picture, the evanescent fields associated with the diverging and converging components of the splash pulse cancel each other identically. The splash pulse is, hence, composed solely of backward and forward propagating components of the Whittaker type.
