    Area of Science:

    • Optics and Photonics
    • Quantum Mechanics
    • Classical Electrodynamics

    Background:

    • Conventional theories of light propagation rely on the wave superposition principle.
    • Existing models struggle to unify interference and diffraction phenomena for both light and single particles.
    • A need exists for a comprehensive theoretical framework addressing arbitrary spatial coherence.

    Purpose of the Study:

    • To present a novel propagation principle for light under arbitrary spatial coherence.
    • To develop a unified phenomenological framework for interference and diffraction.
    • To extend this framework to encompass single-particle interference and diffraction.

    Main Methods:

    • Utilizing a geometrical interpretation of the two-point correlation function.
    • Introducing the concept of geometrical potential.
    • Modeling interactions between real and virtual point emitters.

    Main Results:

    • Established a new principle for light propagation based on point emitter interactions.
    • Developed a complete theoretical model unifying interference and diffraction.
    • Demonstrated applicability to both light and single particles, overcoming limitations of wave superposition.

    Conclusions:

    • The proposed geometrical model provides a unified framework for wave-particle duality phenomena.
    • This approach offers a more comprehensive understanding of interference and diffraction than traditional methods.
    • The theory successfully bridges classical and quantum descriptions of light and matter waves.
