Abstract
We report the refractive indices and absorption coefficients for four beryllia (BeO) ceramic samples. These dielectric properties have been measured over the range from 4 to 18 cm−1 by use of a Michelson interferometer. The index n, follows the linear relationship n=0.6517 cm3/g×ρ+0.7130 with density, ρ, over the range 2.8<ρ<3.0 g/cm3.
