Plane-Wave Scattering from a Nonchiral Object in a Chiral Environment

摘要

The problem of a nonchiral object in an isotropic chiral medium is analyzedthrough wavefield decomposition and treating the chiral medium as a combination of two nonchiral media. Integral equations for the internal wavefields of the onject 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 form. As numerical examples, certain measurable polarization quantities are presented together with their interpretation. The theory is applicable, for example, in analyzing data obtained from measuring the glucose content of blood in terms of light scattered from blood cells.
