Summary[edit]

Description
English: Amplitude chart for a scalar plain wave diffraction on a slit of width being 6 wavelengths; Dirichlet boundary condition.


Computed using 1800 "Green function" sources placed across the slit. Green functions are modified by flipping their sign prior to the slit. Amplitudes are found by solving a linear system that comes from the requirement that the contribution from (modified) Green functions eliminates the x-derivative discontinuity across the slit of the incident+reflected wave prior to the screen (sin(kx)|x<0). Green functions are given by Hankel(1,kR)*x/R.
