|Abstract:||In this dissertation, the design of a multilayer ferrite Radar Absorber with Frequency Selective Surfaces (FSS) embedded on it is described. Emphasis is given on producing better attenuation at a lesser thickness level. Emphasis is also given on measuring Radar Cross Section (RCS) of different kind of shapes like Circular Plate, Cylinder and Cone which more resembles to practical targets. Frequency Selective Surfaces are designed using Genetic Algorithm. Both ferrite layers and FSS are implemented on Aluminum sheets and other shapes. Attenuation is measured using ATD (Absorber Testing Device). RCS is also measured by using monostatic Radar Reflectivity arrangement. Attenuation up to 14 dB is obtained in ATD method and up to 45.75% of reduction in RCS is achieved form RCS measurement. Comparison of the performance of, different layers is drawn and also a comparison is shown in the attenuation level of ferrite absorbers with and without FSS.|
