Abstract:
A discussion is presented of the quantitative results based on the exact solution of the following theoretical problem For a sphere of arbitrary size, composed of homogeneous material with a finite dielectric constant and conductivity, receiving a constant flux of energy from a single direction in the form of plane electromagnetic waves of a given frequency and state of polarization, find the total amount of energy absorbed and scattered by the sphere, as well as the specific intensity and the state of polarization of the energy scattered in a given direction, at a large distance from the sphere. A complete analytical solution to this problem was obtained by Gustav Mie on the basis of Maxwellian field theory. The present study gives accurate numerical results, based on Mies expressions, for a wide range of basic parameters not treated earlier. Illustrated and discussed by means of selected examples are the effects of variations in dielectric and conducting properties on the total scattering and absorption cross sections as a function of the relative size of the sphere, as well as on the differential amplitude, intensity, and polarization of the scattered energy.
