摘要
用迈克尔逊干涉仪测量了4 ~ 18 cm−1范围内4种铍(BeO)陶瓷样品的折射率和吸收系数。指数n与密度p在2.8 < p < 3.0 g/cc范围内呈线性关系，因此指数随密度变化约为3%。
Dielectric properties of beryllia in the near-millimeter wavelength range
The refractive indices and absorption coefficients of four beryllia (BeO) ceramic samples have been measured between 4 and 18 cm−1 with a Michelson interferometer. The index, n, follows a linear relationship with density, p, over the range 2.8 < p < 3.0 g/cc, and thus exhibits a density-dependent index variation of about 3 percent.
