Fresnel diffraction patterns from fractal apertures : boundaries and circulation, pentaflakes and islands

Christian, JM; McDonaldg, GS; Kotsampaseris, A; Huang, JG

Abstract

We present a theoretical and numerical analysis of near-field diffraction patterns from
hard-edged apertures whose shapes correspond to the iterations of (closed) classic
fractal curves. The Fresnel (paraxial) area integral is transformed into a circulation
around the aperture boundary, and edge waves play a key role in the formulation.
