Abstract: A geometric approach is developed to calculate the region of support for a focused linear array of circular pistons in a lossless medium. Equations are derived describing the boundaries of the region of support for a single piston. The model is expanded to examine the lossy case utilizing a Gaussian distribution to model attenuation in a viscous medium. These results are verified using the Fast Nearfield Method, and the numerical error is evaluated.
