 Bi-isotropic material

Bi-isotropic materials are materials that exhibit isotropic properties in both mechanical and electromagnetic contexts. In simpler terms, these materials have the same mechanical and electromagnetic characteristics regardless of the direction in which they are measured. In mechanical terms, an isotropic material has uniform properties in all directions. This means that its mechanical response (like stress, strain, stiffness, etc.) is the same no matter the orientation of the applied forces.
