  • Asymptotic Values of Some Scattering Parameters from Mie Theory 
    Shah, G. A (Indian Institute of Astrophysics, Bangalore, 1991)
    The scattering parameters such as extinction efficiency, albedo, asymmetry parameter, etc, have been studied on the basis of the Mie theory of scattering of electromagnetic radiation by a sphere as well as the classical ...
  • Numerical Evaluation of Spherical Bessel and Related Functions 
    Shah, G. A (Indian Institute of Astrophysics, Bangalore, 1983)
    Techniques for calculating the spherical Bessel functions of complex argument lying in any quadrant of the z-plane and arbitary orders have been developed. The method applies to real, pure imaginary or complex arguments. ...
  • Numerical Methods for Mie Theory of Scattering by a Sphere 
    Shah, G. A (Indian Institute of Astrophysics, Bangalore, 1977)
    A new procedure for evaluating the basic quantities connected with the Mie theory of scattering by a sphere is presented. Some independent numerical techniques are developed to enable one to achieve the desired accuracy. ...
  • Reflection Nebula in the Far Ultraviolet: Icy Grains 
    Shah, G. A; Krishna Swamy, K. S (Indian Institute of Astrophysics, Bangalore, 1978)
    Some models of the reflection nebula in the form of homogeneous plane parallel slab containing singly scattering dirty ice grains as test case have been given. The three geometric cases of the star behind, within and in ...
  • Reflection nebula in the far-ultraviolet. 2. Silicate and graphite grains 
    Shah, G. A; Krishna Swamy, K. S (Indian Institute of Astrophysics, 1979-11)
    Simple models of the reflection nebula in the form of homogeneous plane-parallel slab containing single scattering silicate and graphite grains taken one species at a time have been considered in view of the far-ultraviolet ...
