Abstract
This paper investigates, graphically, a simulation of the launching of recently obtained superluminal localized wave solutions of the homoge neous wave equation. These solutions represent focused interference pa tterns that travel with speed greater than c in the direction of propa gation. Graphical simulation indicates that approximations to these so lutions may be launched from a finite array of point sources, and the superluminal nature of the launched pulses is maintained in the near f ield of the array.
