  1. biaxial, biaxal, biaxateadjective

    having two axes

    "biaxial crystals"


  1. biaxialadjective

    Having two axes

  2. biaxialadjective

    Having a value in two perpendicular directions. [In solid mechanics it generally means that normal stresses exist in two of the possible three directions. Note that they do not have to be equal in sign or magnitude.]


  1. biaxial

    In crystal optics, the index ellipsoid (also known as the optical indicatrix or sometimes as the dielectric ellipsoid) is a geometric construction which concisely represents the refractive indices and associated polarizations of light, as functions of the orientation of the wavefront, in a doubly-refractive crystal (provided that the crystal does not exhibit optical rotation). When this ellipsoid is cut through its center by a plane parallel to the wavefront, the resulting intersection (called a central section or diametral section) is an ellipse whose major and minor semiaxes have lengths equal to the two refractive indices for that orientation of the wavefront, and have the directions of the respective polarizations as expressed by the electric displacement vector D. The principal semiaxes of the index ellipsoid are called the principal refractive indices.It follows from the sectioning procedure that each principal semiaxis of the ellipsoid is generally not the refractive index for propagation in the direction of that semiaxis, but rather the refractive index for wavefronts tangential to that direction, with the D vector parallel to that direction, propagating perpendicular to that direction. Thus the direction of propagation (normal to the wavefront) to which each principal refractive index applies is in the plane perpendicular to the associated principal semiaxis.


  1. biaxial

    Biaxial generally refers to something that has or involves two axes. It commonly refers to a material or object that has different properties along two different axes. It is a term used in various fields including physics, crystallography, and mechanical engineering.
