摘要

Limited diffraction beams could have applications in medicalnimaging, tissue characterization, and nondestructive evaluation, as wellnas other wave related areas such as electromagnetics and optics. In thisnpaper, we develop a novel approach that can convert any diffractingnsolution of the isotropic-homogeneous wave equation to a limitedndiffraction solution. As an example, this approach was applied to annn-dimensional wavelet solution that we generalized from thenthree-dimensional solution obtained by Kaiser et al. (1992). Thisnexample establishes a relationship between localized limited diffractionnbeams and the wavelet theory. The resulting limited diffraction beam wasncompared with those discovered previously
