1. The quality or state of being anisotropic; the property of having different physical or optical characteristics in different directions.
Usage: plural form of anisotropy; commonly used in physics, materials science, and optics

Examples

• The anisotropies in the crystal structure affect how light passes through the material.
• Researchers measured the anisotropies of the magnetic field across different spatial directions.
• The fabric's anisotropies make it stronger along the grain than across it.
• Cosmic microwave background anisotropies provide evidence about the early universe.
• The anisotropies in the rock samples indicated directional stress during formation.
