Factors Toward The Development Of A Robust Surface Plasmon
... the surface plasmon polariton (SPP) is formed, these particles starts propagating along the metal-dielectric interface with amplitudes decaying into both layers. SPP is used to overcome diffraction limit. This leads to the fabrication of photonic devices at very smaller scales than those currently a ...

Laser Doppler Flowmetry - a Theoretical Framework
... The CMBC and Perf estimates in equation 5.2 and 5.3 depend on the total light intensity, or the static part of the photocurrent, idc (see equation 4.8). Therefore, in the practical situation the estimates should be normalised with a factor that compensates for this dependency. In LDPM devices the es ...

Overview of various methods for measuring a lens focal length
... This technique uses the Talbot effect: the image of a coherent wave with 2D periodic amplitude distribution, incident upon a diffraction grating, is regularly repeated. The distance between each self-image is the Talbot length ∆. If the wave interferes with another wave diffracted by a grating with ...

Thomas Young (scientist)
.jpg?width=300)
Thomas Young (13 June 1773 – 10 May 1829) was an English polymath and physician. Young made notable scientific contributions to the fields of vision, light, solid mechanics, energy, physiology, language, musical harmony, and Egyptology. He ""made a number of original and insightful innovations""in the decipherment of Egyptian hieroglyphs (specifically the Rosetta Stone) before Jean-François Champollion eventually expanded on his work. He was mentioned by, among others, William Herschel, Hermann von Helmholtz, James Clerk Maxwell, and Albert Einstein. Young has been described as ""The Last Man Who Knew Everything"".
