title: Huygens's secondary-sources dimensions.
abstract: Using a vectorial formulation, we show that Huygens's secondary-sources density is constant in plane waves, and it depends only on the wavelength. We also illustrate that Huygens's secondary sources, which act as emitters of secondary wavelets, have a finite dimension equal to 3 pi/2k(2).
