Grating Equation. The general grating equation is usually written as: nλ = d(sin i + sin i’) where n is the order of diffraction, is the diffracted wavelength, d is the grating constant (the distance between successive grooves), i is the angle of incidence measured from the normal and i’ is the angle of diffraction measured from the normal.
Engineering Mathematics with Examples and Applications provides a compact and concise primer in the field, starting with the foundations, and then gradually developing to the advanced level of mathematics that is necessary for all engineering disciplines. Therefore, this book's aim is to help undergraduates rapidly develop the fundamental knowledge of engineering mathematics.

This study develops a strain measurement model for beam structures subjected to multiloading conditions by defining the strain-shape function and participation factors to overcome the limitations of strain measurements using fiber Bragg grating (FBG) strain sensors. Using the proposed model, the maximum strain in a beam is obtained by the sum of the strains caused by the different loadings
Introduction to Diffraction Grating Diffraction Gratings (Ruled and Holographic) Diffraction gratings can be divided into two basic categories: holographic and ruled. A ruled grating is produced by physically forming grooves on a reflective surface by using a diamond tool mounted on a ruling engine. The distance between adjacent
Diffraction Grating Handbook - Chapter 1 . THE GRATING EQUATION [top] When monochromatic light is incident on a grating surface, it is diffracted into discrete directions. We can picture each grating groove as being a very small, slit-shaped source of diffracted light. The light diffracted by each groove combines to form a diffracted wavefront.
Here, we report the fabrication of a graphene-based Bragg grating (one-dimensional photonic crystal) and experimentally demonstrate the excitation of surface electromagnetic waves in the periodic

A magnetostrictive-fiber Bragg grating sensor for induction motor health monitoring. In this last equation we adopted the technique of building a magnetostrictive material around the FBG. This was done in order to obtain a small, robust and compact sensor, capable to be inserted into a small hole to be made in the motor stator core.
Surface plasmon polaritons (SPPs) are infrared or visible-frequency electromagnetic waves that travel along a metal–dielectric or metal–air interface. The term "surface plasmon polariton" explains that the wave involves both charge motion in the metal ("surface plasmon") and electromagnetic waves in the air or dielectric ("polariton").

The Grating Equation. A typical diffraction grating comprises a substrate of an optical material with numerous parallel grooves ruled or reproduced on its surface. The substrate is coated with a reflecting material like aluminum. The quality and spacing of the grooves are significant to the performance of the grating.
This section provides an overview of Unit 1, Part B: Matrices and Systems of Equations, and links to separate pages for each session containing lecture notes, videos, and other related materials.
In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.

Fiber Bragg Gratings are made by laterally exposing the core of a single-mode fiber to a periodic pattern of intense laser light. The exposure produces a permanent increase in the refractive index of the fiber‘s core, creating a fixed index modulation according to the exposure pattern. This fixed index modulation is called a grating.
