Back-of-the-envelope calculations are too crude and naive numerical approaches too expensive. However, a combination of mathematical and numerical techniques yields elegant tools. We survey these approaches.

Wavefield Representation Using Compact and Directionally Localized Sources,ipole expansion, and may be preferable if the source is highly directional. In the high frequency limit the far-field pattern function is proportional to the associated weighting function for the complex sources. The theory is developed for both 2D and 3D, and numerical examples are presented for a 3D end-fire array.
