Half-Wave Zone Single-Slit Modeling: Visualizing Near-Field Diffraction and Complex Diffraction Integrals
This applet is an enhanced version of our previous applet for visualising near-field single-slit diffraction. It introduces the ability to visualise the complex vector summation from half-wave zones at an arbitrary point in the observation plane. Earlier versions, applets 1 and 2, were limited to the central axis.
