WebThe diffraction formula is based on scalar diffraction theory, which ignores polarization effects. In some situations, ignor-ing polarization is benign, but in other situations, ignoring polarization effects produces signiﬁcant errors. These issues as well as the approximations leading to scalar diffraction theory are discussed in section10.2. WebDiffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the word …
