isotrope

The meaning of isotrope is: "identical in all directions". The opposite is anisotrope (diffenrent in different dirctions).

Materials have isotropic character if their properties, for example stiffness or  conductivity, are identical independent from the direction they are measured.

A plasma process may operate isotropic or anisotropic depending of methods and parameters applied. Chemical Etching usually operates isotropic.
