The propagating and evanescent field components of localized wave solutions
نویسندگان
چکیده
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.

Aperture realizations of exact solutions to homogeneous-wave equations
Received January 21, 1992; revised manuscript received July 13, 1992; accepted July 28, 1992 Several new classes of localized solutions to the homogeneous scalar wave and Maxwell's equations have been reported recently. Theoretical and experimental results have now clearly demonstrated that remarkably good approximations to these acoustic and electromagnetic localized-wave solutions can be achi...
متن کاملNon -propagating Waves and Behavior of Curtainwall-pile Breakwaters
Abstract Usually, evanescent modes or non-propagating waves are produced when a propagating incident wave impinges on an interface between two media or materials such as curtainwall-pile breakwater (CPB) at a subcritical angle and decay with distance from interface. To achieve an effective prediction of hydrodynamic performance of CPB and overcome the problem of underestimation of energy loss, ...
متن کاملEvanescent field of vectorial highly non-paraxial beams.
In terms of the Fourier spectrum, a simple but general analytical expression is given for the evanescent field associated to a certain kind of non-paraxial exact solutions of the Maxwell equations. This expression enables one to compare the relative weight of the evanescent wave with regard to the propagating field. In addition, in those cases in which the evanescent term is significant, the ma...
متن کاملBehavior of Propagating and Evanescent Components in Azimuthally-polarized Nonparaxial Fields
The contribution of the propagating and the evanescent waves associated with freely propagating nonparaxial light fields whose transverse component is azimuthally polarized at some plane is investigated. Analytic expressions are derived for describing both the spatial shape and the relative weight of the propagating and the evanescent components integrated over the transverse plane. The analysi...
متن کاملOn the evanescent fields and the causality of the focus wave modes
The diverging and converging field components of the source-free focus wave modes are studied within the framework of both the Whittaker and Weyl plane wave expansions. It is shown that, in the Weyl picture, the evanescent fields associated with the diverging and converging components of the focus wave mode solution cancel each other identically. The source-free focus wave modes are, hence, com...
