In the physical sciences

• Polarization (waves), the ability of waves to oscillate in more than one direction, in particular polarization of light, responsible for example for the glare-reducing effect of polarized sunglasses
  • Polarization (antenna), the state of polarization (in the above sense) of electromagnetic waves transmitted by or received by a radio antenna
• Dielectric polarization, charge separation in insulating materials:
  • Polarization density, volume dielectric polarization
  • Dipolar polarization, orientation of permanent dipoles
  • Ionic polarization, displacement of ions in a crystal
  • Maxwell-Wagner-Sillars polarization, slow long-distance charge separation in dielectric spectroscopy on inhomogeneous soft matter
• Polarization (electrochemistry), a change in the equilibrium potential of an electrochemical reaction
• Concentration polarization, the shift of the electrochemical potential difference across an electrochemical cell from its equilibrium value
• Spin polarization, the degree by which the spin of elementary particles is aligned to a given direction
• Polarizability, an electrical property of atoms or molecules and a separate magnetic property of subatomic particles
  • Polarization function, a feature of some molecular modelling methods
• Photon polarization, the mathematical link between wave polarization and spin polarization
• Vacuum polarization, a process in which a background electromagnetic field produces virtual electron-positron pairs

In mathematics
