Plane-wave scattering from a nonchiral object in a chiral environment

The problem of a nonchiral object in an isotropic medium is analyzed through wave-field decomposition and treatment of the chiral medium as a combination of two nonchiral media. Integral equations for the internal wave fields of the object are formed, suitable for numerical computation. For an object with small contrast, solutions are found through the Born approximation. As a special case, a spherical object is considered and expressions for the scattered far fields are found in explicit analytical form. As numerical examples, certain measurable polarization quantities are presented together with their interpretation. The theory is applicable, for example, to the analysis of data obtained from the measurement of the glucose content of blood in terms of light scattered from blood cells.
