Optical characteristics of materials
- Our brief introductory notes
on optical characterization of media
define different optical parameters
(including the refractive index, dielectric permittivity,
absorption coefficient, reflectance, transmittance)
and show their relationship. Attention is also paid
to the permittivity tensor arrising for anisotropic
materials and the oscillator model of the permittivity.
Some books for further reading are mentioned as well.
- Our remarks
on the optical constants of cosmic dust analogs
diplay the situation with these constants in 2002
and, for the sake of illustration, point out several
astronomical problems where they play an important role.
A Postscript version of the remarks is here.
for Astronomy (JPDOC)
is linked to this site.
The JPDOC contains data measured in broad wavelength ranges and partly
at low temperatures in the laboratory of the Friedrich Schiller University
Jena (Germany) as well as references to papers and links to
internet resources related to measurements or calculations of the
optical constants of materials of astronomical interest.
A brief description of the JPDOC
was printed in the A&A Suppl (the Postscript version of the paper is here).
The current state (by the end of 2002) and our future plans are
described in the paper printed in the JQSRT
(its Postscript version is here).
