# How can the Huygens-Fresnel principle be derived from the Maxwell equations?

The Huygens-Fresnel principle states that every point to which a luminous disturbance reaches becomes a source of a spherical wave. I have been trying to understand this considering a infinite screen with a microscopic hole $dS$ on which a plane wave is incident, but I see no obvious way to describe the resulting propagating wave.

How can it be derived from the Maxwell equations?

What level of physics are you at? The rigorous way to solve this problem involves Greens' function solutions –  Jerry Schirmer Jun 12 '12 at 13:54
I'd say at the level of Jackson's Classical Electrodynamics. –  Whelp Jun 13 '12 at 20:35
