Etymology

From anti- + mirror.

Meanings

1. An antisymmetric operation; the operation of reflection combined with a reversal of some sort (such as color, time, size, etc); the reflection of opposites.
   • The conditions are often signs of a triumphant hero's beginnings, and indeed will almost reflect, in the antimirror, Cordelia's fate. 1992, Marvin Rosenberg, The Masks of King Lear:
   • A physical system may be invariant under mirror operations, but also under antimirror operations, that is mirror operations combined with time reversal. 1994, American Journal of Physics - Volume 62, page 328:
   • When an antimirror plane is positioned between the two halves of the Herman's logo, or between the man and woman in the Russian sculpture, there is no geometrical correspondence between the two parts. 1994, István Hargittai, Magdolna Hargittai, Symmetry: A Unifying Concept, page 116:
   • Because of their color reversing nature, antioperations act on displacements such as p in a manner complementary to the action of ordinary symmetry operations; in the present case the antimirror acts to invert the component of p responsible for breaking the symmetry, i.e., p*, and leaves invariant the normal (expansion) component, which does not break symmetry; 1994, R.C. Pond & J.P. Hirth, “Defects at Surfaces and Interfaces”, in Advances in Research and Applications, page 347:
2. Something that inhibits reflection; something that obscures or absorbs light instead of reflecting.
   • The veil, in some of the poems I have discussed, functions as a kind of antimirror: a representation of the hidden side of nature. 2013, Andrew Mattison, The Unimagined in the English Renaissance, page 155:
   • Point is, the west wall had to have zero albedo, no reflection, the opposite of the Gymsealed floor. Actually, that's how I wanted my face to be. The Yid called it a "Light Sponge" or an "antimirror." 2007, Eliot Fintushel, Breakfast with the Ones You Love:
   • The current disruption simulation was performed with a long "antimirror" trap 2MK-200 at 10 MW/cm² flow density. 1994, Plasma Physics Reports - Volume 20, page 931:
