Scale = 0.5;
Box_y = Box_x/Scale;

Nx = 200;
Ny = Nx/Scale;

wavenumber = 10;

hy = YY(2) - YY(1);
[X, Y] = meshgrid(XX, YY);

This math image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Plane wave.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
