anisotropic

 [an-i″so-trop´ik]
1. having unlike properties in different directions.
2. doubly refracting, or having a double polarizing power.
3. in cardiac physiology, having nonuniform conduction; used to describe the nonuniform characteristics of the myocardium in the direction perpendicular to the conduction direction of a fiber. See also isotropic.

an·i·so·tro·pic

(an-ī'sō-trop'ik),
Not having properties that are the same in all directions.
[aniso- + G. tropos, a turning]

an·i·so·tro·pic

(an-īsō-trōpik)
Not having properties that are the same in all directions.
[aniso- + G. tropos, a turning]

anisotropic 

State of an optical medium in which the optical properties are not the same in all directions, due to the fact that the refractive index is not the same for all directions. An incident ray will be divided, within a uniaxial anisotropic medium, into two refracted rays; an ordinary ray which obeys Snell's law and an extraordinary ray which follows a different law. Most crystals are anisotropic. See birefringence; dichroism; isotropic.

an·i·so·tro·pic

(an-īsō-trōpik)
