A radar absorbing structure composite (RAS) which contains circuit analogue structure (CAS) made from conductive foil was studied in this paper. The results show that CAS acting as a reflection screen can cause the interference of incident EM wave with reflection EM wave. So, through rational composite material design and preparation, the radar absorbing structure composite with CAS can exhibit good radar absorbing property. The results also show that in the composites with gradually changed impedance, when other design parameters are not changed but only increase the size of CAS, the electromagnetic parameter and the thickness of the medium laminate, the maximum absorbing peak of the reflectivity will move to the direction of the lower frequency. The above research results show that the introduction of CAS into the radar absorbing structure composites can improve the wave-absorbing properties. Therefore the radar absorbing structure composite with CAS is a promising radar absorbing structure composite form.
