The Huygens-Fresnel principle can be derived by integrating over a different closed surface.
These effects can be modelled using the Huygens-Fresnel principle.
See the article Huygens-Fresnel principle for more information.
The Huygens-Fresnel principle, a simple model to understand disturbances in wave propagation.
The Huygens-Fresnel principle provides a good basis for understanding and predicting the wave propagation of light.
The Huygens-Fresnel principle describes diffraction of wave propagation between two fields.
All these waves add up to give specular reflection and refraction, according to the Huygens-Fresnel principle.
So the spatial domain operation of a linear optical system is analogous in this way to the Huygens-Fresnel principle.
(Although a quantum phenomenon, this can be visualized in simple classical terms by the Huygens-Fresnel principle.)
Examples of the application of Huygens-Fresnel principle can be found in the sections on diffraction and Fraunhofer diffraction.
'Fourier optics' is the study of classical optics using techniques involving Fourier transforms and can be seen as an extension of the Huygens-Fresnel principle.
It deals with wave fronts and their normal rays, with propagation conceived by means of spherical waves emitted along the wave front (see also Huygens-Fresnel principle).
The various assumptions made by Fresnel emerge automatically in Kirchhoff's diffraction formula, to which the Huygens-Fresnel principle can be considered to be an approximation.
Diffraction arises because of the way in which waves propagate; this is described by the Huygens-Fresnel principle and the principle of superposition of waves.
The knife-edge effect is explained by Huygens-Fresnel principle, which states that a well-defined obstruction to an electromagnetic wave acts as a secondary source, and creates a new wavefront.
The Huygens-Fresnel principle gives the diffraction formula for two fields U(x,y), U(x,y) as following:
The same logic is used in connection with the Huygens-Fresnel principle, or Stratton-Chu formulation, wherein the "impulse response" is referred to as the Green's function of the system.
The specific transduction method has no impact on the directivity of the resulting sound field; the analysis relies only on the aperture function of the source, per the Huygens-Fresnel principle.
The resulting Huygens-Fresnel principle was extremely successful at reproducing light's behavior and, subsequently supported by Thomas Young's discovery of double-slit interference, was the beginning of the end for the particle light camp.
Stated another way, the radiation pattern of any planar field distribution is the FT of that source distribution (see Huygens-Fresnel principle, wherein the same equation is developed using a Green's function approach).
The first physical optics model of diffraction that relied on the Huygens-Fresnel principle was developed in 1803 by Thomas Young in his interference experiments with the interference patterns of two closely spaced slits.
In his 1678 Traité de la Lumiere, Christiaan Huygens showed how Snell's law of sines could be explained by, or derived from, the wave nature of light, using what we have come to call the Huygens-Fresnel principle.
Poisson, relying on intuition rather than mathematics or scientific experiment, ridiculed participant and civil engineer Augustin-Jean Fresnel when he submitted a thesis explaining diffraction derived from analysis of both the Huygens-Fresnel principle and Young's double slit experiment.
The Huygens-Fresnel principle (named after Dutch physicist Christiaan Huygens and French physicist Augustin-Jean Fresnel) is a method of analysis applied to problems of wave propagation both in the far-field limit and in near-field diffraction.
The Huygens-Fresnel principle is one such model; it states that each point on a wavefront generates a secondary spherical wavelet, and that the disturbance at any subsequent point can be found by summing the contributions of the individual wavelets at that point.
