Background Information

The Fast Nearfield Method

The fast nearfield method, which converges much more rapidly than the point source superposition method or the impulse response, produces accurate numerical results in a fraction of the time required by other approaches. In addition, the FNM has been adapted to transient problems encountered in imaging applications. For time-domain problems, the FNM avoids the temporal aliasing problems associated with the impulse response approach while also providing a fast and efficient method for computing transient fields. Since the field generated by each element is exact in a linear, homogeneous medium, the user does not have to worry about controlling the error in large acoustic calculations. The FMN paper is cited because it exaplains the pratical implementation of analyzing continuous waves when using this method.
