anizotróp

Anizotróp is a term used to describe a material or phenomenon that exhibits different properties in different directions. This is in contrast to isotropic materials, which have uniform properties regardless of the direction of measurement. The word itself comes from the Greek "an-" meaning "not" and "iso-" meaning "equal," combined with "tropos" meaning "turn" or "direction."

Many natural and artificial materials display anisotropy. For example, wood is anisotropic because its strength varies significantly along the grain compared to across the grain. Similarly, crystals often exhibit anisotropic optical or electrical properties. In physics, anisotropy can refer to the directional dependence of physical quantities like magnetic susceptibility, thermal conductivity, or refractive index. The study of anisotropy is crucial in fields such as materials science, solid-state physics, and engineering, as it influences material behavior and performance in various applications. Understanding anisotropy allows for the design and utilization of materials with specific directional characteristics, optimizing their function in devices and structures.
