The apertures of classical optics simply
block those parts of an incident
wavefront that fall outside the aperture,
allowing everything else to go through
intact.Moreover,multiple apertures act
upon an incident beam independently of
each other, polarization effects are usually
negligible (i.e., scalar diffraction),
and it is not necessary to keep track of
both the electric- and the magnetic-field
components of the beam.
