Title: Analysis of on-axis wave focusing through the use of non annular slits
Author: Nobrega, KZ
Dartora, CA
Abstract: In this paper we use the scalar diffraction theory to obtain an analytical procedure allowing someone to localize waves around a spatial range. In fact, we have studied the use of different slits profiles to obtain axial localization considering a simple optical setup. To do this, three kinds of slits named Cube root, Exponential and Sinusoidal were analyzed. (C) 2004 Elsevier B.V. All rights reserved.
