In electromagnetics and communications engineering, a waveguide is defined as any physical structure that guides electromagnetic waves. In optics, however, the term is usually restricted to optical fibres. Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, composed of the electric field and the magnetic field. ...
The term communications is used in a number of disciplines: Communications, also known as communication studies is the academic discipline which studies communication, generally seen as a mixture between media studies and linguistics. ...
Optical dielectric waveguides
 A diagram which illustrates the propagation of light through a multi-mode optical fiber. A dielectric waveguide is a waveguide that consists of a dielectric material surrounded by another dielectric material, such as air, glass, or plastic, with a lower refractive index. An example of a dielectric waveguide is an optical fiber. Image File history File links Diagram showing how light is guided through an optical fibre Incident rays which fall within the acceptance cone of the fiber are transmitted, whereas those which fall outside of the acceptance cone are lost in the cladding. ...
