calculation of radar reflection loss in single-layered case and study on dielectric properties

it is an important issue not only for military purposes but also from commercial point of view, whether or not the reflective wave from an incident electromagnetic wave can be nullified. in this research, by blending conductive carbon black with the binder matrix of glass/epoxy composite, a radar absorbing structure (ras) which can support loads and absorb the electromagnetic wave has been designed. the ras was specially designed so as to exhibit the optimum absorptivity for x-band of (8.2–12 ghz) frequency ranges, centered at 10 ghz. an optimized multi-layer design of ras using the adopted material system is described in this research.
