Anisotropic

All other crystals are anisotropic: light passing through them is broken up into two plane polarized rays that travel at different speeds and refract at different angles.

Anisotropic etching can also refer to certain chemical etchants used to etch a certain material preferentially over certain crystallographic planes (e.

Anisotropic etching Some single crystal materials, such as silicon, will have different etching rates depending on the crystallographic orientation of the substrate.

Anisotropic etch processes, where vertical etch-rate is high, but lateral etch-rate is very small are essential processes in microfabrication of integrated circuits and MEMS devices.

Anisotropic filtering (AF) is a method of enhancing the image quality of textures on surfaces that are far away and steeply angled with respect to the point of view.

Anisotropic magnetoresistance (AMR) The resistance of a thin Permalloy film is shown here as a function of the angle of an applied external field.

Because the etching is performed by ions, which approach the wafer approximately from one direction, this process is highly anisotropic.

Because the permittivity is anisotropic, polarized light of different orientations will travel at different speeds.

Heat conduction is more commonly anisotropic, which implies that detailed geometric modeling of typically diverse materials being thermally managed is required.

Highly anisotropic materials like regular wood (as opposed to wood composites) can easily be wedged apart.

However, an anisotropic sample will generally change the polarization so some of the light can pass through.

In combination with wet anisotropic etching as described above, ECE has been used successfully for controlling silicon diaphragm thickness in commercial piezoresistive silicon pressure sensors.

It also yields two other quantum numbers and the shape of the electron's wave function ("orbital") for the various possible quantum-mechanical states, thus explaining the anisotropic character of atomic bonds.

It was from density fluctuations (or anisotropic irregularities) in this primordial matter that larger structures began to appear.

Liquid crystals are examples of anisotropic liquids.

Metals and alloys tend to be more isotropic, though they can sometimes exhibit significant anisotropic behaviour.

More generally, the imaginary parts of the eigenvalues of the anisotropic dielectric tensor should be considered.

Most materials exhibit anisotropic behavior.

Non-uniform scaling ( anisotropic scaling, inhomogeneous dilation) is obtained when at least one of the scaling factors is different from the others; a special case is directional scaling or stretching (in one direction).

Plasma etching can be isotropic, i.e., exhibiting a lateral undercut rate on a patterned surface approximately the same as its downward etch rate, or can be anisotropic, i.e., exhibiting a smaller lateral undercut rate than its downward etch rate.
