... Constraints on cosmic silicates. ... Optical constants: . O-deficient circumstellar silicate . ... The optical constants of the O-deficient silicate were derived from [C abs (lambda)/V] (C abs and V are the cross-section and volume of grains) derived from observational data using Kramers-Kronig relation and some assumptions on the size and shape distributions of grains. ... The optical constants of the O-rich silicate were obtained in a similar but more complex way. Back to silicate page . ...

... A ray obliquely incident at the cylinder scatters on the surface of a cone (in the far zone) mainly in the forward direction. The results for the cylinder with the radius equal to the wavelength of incident radiation multiplied by 5 / pi ( x =10), the refractive index m=n+k i=1.33 and the angle between the symmetry axis of the particle and the wave-vector of incident radiation alpha =45 o were obtained with one of the codes presented in the DOP.
