Propagation of abrupt autofocusing beam inside scattering media using beam propagation method

Abstract

The cylindrically symmetric airy beam, also known as the abrupt autofocusing (AAF) beam, has unique propagation properties. For precise power delivery at greater penetration depths, such a beam can be highly useful without affecting the surface of tissues or other intermediate planes. In this work using the beam propagation method, the point spread function of abrupt autofocusing beams inside the scattering media in the transition zone from ballistic to diffusive transport of light is explored in detail.
