Wave propagation in optical systems with large apertures
Wave propagation in optical systems with large apertures is a scholarly work, published in 1978 in ''Journal of the Optical Society of America''. The main subjects of the publication include optics, dimensionless quantity, mathematical analysis, diffraction, Aperture, geometrical optics, Fresnel zone antenna, Fresnel equations, limit, Fresnel diffraction, Huygens–Fresnel principle, silicon photonics, Acousto-optics, High frequency approximation, wave propagation, Kirchhoff's diffraction formula, anti-reflective coating, Fresnel integral, Fresnel zone, Fresnel number, physics, and physical optics. The Kirchhoff-Huygens equation is used to investigate wave propagation in optical systems, with large propagation Fresnel numbers NF and aperture-to-length ratios (a/L) which are not small.
