Abstract

The ability to control the bistatic scattering characteristics from cylindrical objects using a tapered cylindrical impedance sheet is presented. It is shown that with the capability to readily control both the real and imaginary components of a percolated lossy film´s effective impedance, specific impedance distributions can be obtained to effectively introduce and direct the overall nulls in the bistatic scattering pattern. The bistatic scattering width calculations are based on a modal analysis and an impedance-sheet boundary condition formulation. Potential uses of tapered cylindrical impedance sheets in bistatic EMC/EMI applications are discussed.
