Reflector (cipher machine) - A reflector, in cryptology, is a component of some rotor cipher machines, such as the Enigma machine, that sends electrical impulses that have reached it from the machine's rotors, back in reverse order through those rotors. The reflector is also known as the reversing drum or, from the German, the Umkehrwalze or UKW.
Spherical reflector - A spherical reflector is a reflector shaped like a portion of a sphere, so that light (or other electromagnetic radiation such as radio waves) from a point-source located at the virtual centre point of the sphere will reflect off the mirrored surface and back through the ...
Distributed Bragg reflector - In guided wave optics, a distributed Bragg reflector (DBR) is a structure formed from multiple layers of alternating materials with varying refractive index, or by periodic variation of some characteristic (such as height) of a dielectric wave guide, resulting in periodic variation in the effective refractive index in the guide. Each layer boundary causes a partial reflection of an optical wave, and for waves with optical wavelength such that the many reflections combine with constructive interference, a high quality reflector is formed.
Toroidal reflector - A toroidal mirror is a form of parabolic reflector which has a different focal distance depending on the angle of the mirror. The curvature is actually that of an elliptic paraboloid with a \ne b.
