Scattering from Layered Targets. 1. Formulas for the Scattering Coefficients for a Multilayered Sphere

摘要

The layering of targets provides a means of enhancing or decreasing the radar cross-section over a resonance region which can be centered at a desired frequency and increased in extent by suitable practical adjustments of material constants. When one is calculating results in the resonance region all of the quantities of interest, which include the angular scattering and absorption, are obtained by summing generalized Mie series which contain the scattering coefficients. In this note a simple formulation for these coefficients is given for a composite sphere composed of any number of homogeneous but otherwise arbitrary concentric spheres. (Author)
