The Goos–Hänchen effect (named after Hermann Fritz Gustav Goos (1883–1968) and Hilda Hänchen (1919–2013) is an optical phenomenon in which linearly polarized light undergoes a small lateral shift when totally internally reflected. The shift is perpendicular to the direction of propagation in the plane containing the incident and ...
The technique was developed by Jean Gaudin in Paris in the 1930s. Slabs of coloured glass, 20 centimetres (7.9 in) to 30 centimetres (12 in) square or rectangular and typically up to 3 centimetres (1.2 in) thick, are shaped by breaking with a hammer or cutting with a saw.
The shading coefficient depends on the color of glass and degree of reflectivity. It also depends on the type of reflective metal oxides for the case of reflective glass. Sputter-coated reflective and/or sputter-coated low-emissivity glasses tend to have lower SC compared to the same pyrolitically-coated reflective and/or low-emissivity glass.
The calculation of glass properties allows "fine-tuning" of desired material characteristics, e.g., the refractive index. [1]The calculation of glass properties (glass modeling) is used to predict glass properties of interest or glass behavior under certain conditions (e.g., during production) without experimental investigation, based on past data and experience, with the intention to save ...
The phase shift is =, which causes fringes to shift in proportion to and . At non-relativistic speeds, the Sagnac effect is a simple consequence of the source independence of the speed of light. In other words, the Sagnac experiment does not distinguish between pre-relativistic physics and relativistic physics.
Unlike a standard lens, a binary zone plate produces intensity maxima along the axis of the plate at odd fractions (f/3, f/5, f/7, etc.).Although these contain less energy (counts of the spot) than the principal focus (because it is wider), they have the same maximum intensity (counts/m 2).
The function is named in honor of von Hann, who used the three-term weighted average smoothing technique on meteorological data. [6] [2] However, the term Hanning function is also conventionally used, [7] derived from the paper in which the term hanning a signal was used to mean applying the Hann window to it.
Ion stuffing – Phase separation of a specific glass causes pores to form, which can later be filled using a variety of salts or concentration of salts to give a varying gradient. [ 6 ] [ 13 ] Direct laser writing – While point-by-point exposing the pre-designed structure an exposure dose is varied (scanning speed, laser power, etc.).
