All accepted papers will be published in Physica Scripta, a monthly international journal for experimental and theoretical physics. A limited number of registrations are available from this office. Wavelength Selective Surface Coating for Aluminum . A process has been developed by the Institute for Energy Technology in Kjeller, Norway, which results in a dark-colored, wavelength selective oxide film on aluminum. The resulting surface is very absorbing below 1 micron and very reflective above 4 microns, reportedly caused by 100 Angstrom metal particles in the-oxide.
Experimental data is available.
