anisotropy

American  

[an-ahy-so-truh-pee] / ˌæn aɪˈsɒ trə pi /

Rarely anisotropism

noun

1. Physics. the fact of having unequal physical properties along different axes.

   Even crystals with a simple cubic lattice structure, such as salt, display optical anisotropy; that is, the light propagates differently in different directions.

2. Botany. the fact of having different rates of growth in different directions.

   Anisotropy is a nearly ubiquitous feature of plant growth; it is necessary, if a growing plant organ is to produce any other form than a sphere.

As a result, the crystal behaves like a metal along one axis and like a dielectric material along the perpendicular axis, creating its exceptionally strong anisotropy.
