Synthetic Aperture Simulation

Synthetic Aperture / Beamforming is a basic technique used across many fields. By aligning the phase of the wave from each emitter to overlap at a specific point, constructive and destructive interference can be controlled and shaped.

Waves, of course, can move across any medium, from water to light - I am specifically interested in how it might apply to lightfield rendering, and
acoustic/magnetic levitation.

This visualization displays the underlying priciple of aligning the phase, and is only a step away from physical application.
