Area of Science:

  • Optics and electromagnetism
  • Mathematical physics

Background:

  • Huygens' principle and Kirchhoff's method are widely used for diffraction problems but have limitations.
  • Existing methods struggle with non-paraxial diffraction and complex geometries.
  • A need exists for a more versatile and mathematically rigorous diffraction theory.

Purpose of the Study:

  • To develop a physically based and mathematically strict "dipole wave" vector theory for non-paraxial electromagnetic radiation diffraction.
  • To enable analytical solutions for typical diffraction problems with broader applicability.
  • To provide a more robust alternative to the Kirchhoff method.

Main Methods:

  • The study employs the Hertz vector within the Kirchhoff integral formulation.
  • This vector approach is used instead of the traditional field vector.

    • Main Results:

    • Analytical solutions for diffraction on infinite slits and various holes were obtained for arbitrary incidence and polarization.
    • The vector addition of solutions allows for the analysis of diffraction patterns from multiple apertures.
    • Unique "poles" (zero-field points) were identified in diffraction patterns, aligned with electric field vectors.
    • Formulas for laser beam propagation in free space were derived.

    Conclusions:

    • The dipole wave theory provides a powerful tool for solving non-paraxial diffraction problems analytically.
    • The theory overcomes the applicability limitations of the Kirchhoff method.
    • The findings offer new insights into electromagnetic wave propagation and diffraction phenomena.
