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.
