Abstract

The application of chiral composites in the reduction of the radar cross section is now well established. In this paper, the extended T-matrix method and the modified MIE solutions are used t compute RCS reduction possible with chiral coatings. Several scatterer shapes including the sphere, cylinder and oblate spheroid have been taken up for illustration. The RCS reduction obtained using chiral coatings has been compared with conventional RAMs. In all cases an RCS reduction of around 10 - 15 dB better than RAM and over a wide frequency range has been observed. A brief discussion on the possible mechanisms that can be attributed to cause this reduction in RCS is also included.
