Description

This course covers algebraic approaches to electromagnetism and nano-photonics. Topics include photonic crystals, waveguides, perturbation theory, diffraction, computational methods, applications to integrated optical devices, and fiber-optic systems. Emphasis is placed on abstract algebraic approaches rather than detailed solutions of partial differential equations, the latter being done by computers.

Find out what solid-state physics has brought to Electromagnetism in the last 20 years. This course surveys the physics and mathematics of nanophotonics—electromagnetic waves in media structured on the scale of the wavelength. Topics include computational methods combined with high-level algebraic techniques borrowed from solid-state quantum mechanics: linear algebra and eigensystems, group theory, Bloch's theorem and conservation laws, perturbation methods, and coupled-mode theories, to understand surprising optical phenomena from band gaps to slow light to nonlinear filters. Note: An earlier version of this course was published on OCW as 18.325 Topics in Applied Mathematics: Mathematical Methods in Nanophotonics, Fall 2005.

Rocks are made of minerals and, as minerals are natural crystals, the geological world is mostly a crystalline world. This free course, Minerals and the crystalline state, introduces the study of minerals and crystal structures, using online text and interactive activities, including questions and answers, video clips, slidecasts and a Digital Kit. First published on Tue, 22 Mar 2016 as Minerals and the crystalline state. To find out more visit The Open University's Openlearn website.

CORE-Materials posted a photo: This picture shows a pattern for Penrose tiling, which was constructed using the Penrose substitution rule: the projection is from a lattice in five dimensions to the plane. A Penrose tiling is a non-periodic tiling generated by an aperiodic set of prototiles named after Sir Roger Penrose, who investigated these sets in the 1970s. The aperiodicity of the Penrose prototiles implies that a shifted copy of a Penrose tiling will never match the original. Eventually, it emerged that the atoms in tquasicrystals were arranged like Penrose tiling patterns. Courtesy of Edmund Harriss, Department of Mathematical Sciences, University of Arkansas.License

Description

This lecture provides an introduction to metallurgical concepts necessary to understand how structural features of aluminium alloys are influenced by alloy composition, processing and heat treatment, and the basic affects of these parameters on the mechanical properties, and hence engineering applications, of the alloys. It is assumed that the reader has some elementary knowledge of physics, chemistry and mathematics.Subjects

The basic objective of Unified Engineering is to give a solid understanding of the fundamental disciplines of aerospace engineering, as well as their interrelationships and applications. These disciplines are Materials and Structures (M); Computers and Programming (C); Fluid Mechanics (F); Thermodynamics (T); Propulsion (P); and Signals and Systems (S). In choosing to teach these subjects in a unified manner, the instructors seek to explain the common intellectual threads in these disciplines, as well as their combined application to solve engineering Systems Problems (SP). Throughout the year, the instructors emphasize the connections among the disciplines.Subjects

Phase transformation when an isotropic liquid changes to a nematic liquid crystal (magnification 20x, speed 3x). As the temperature decreases the coloured liquid crystalline phase begins to nucleate at various random points across the slide. Darker regions are visible where the director is aligned with either the polariser or the analyser.

Description

Phase transformation (20x magnification, 4x speed) for isotropic liquid to nematic liquid crystal (on grooved surface). The elongated liquid crystal molecules tend to orientate along the scratches as does nucleation of the liquid crystalline phase, with the liquid crystal sweeping in from the side rather than appearing at random points.

See all metadataPhase transformation from an isotropic liquid to a chiral nematic liquid crystal

Description

Phase transformation (20x magnification, 3x speed) for an isotropic liquid to chiral nematic liquid crystal. Although nucleation begins in a similar fashion to the regular nematic, we can see the different regions merge with one another to form the final 'fingerprint structure' that is characteristic of chiral nematics with their helical axis parallel to the surface of the slide.
