The dielectric properties of the fabricated nano-composites were measured using a free space measurement system (HVS Technologies, Pennsylvania, USA). The nano-composites composed of the E-glass/epoxy composites and nano-size carbon black were fabricated with respect to the weight percents (wt.%) of the carbon black. Based on the theoretical calculation and investigation, an optimum design method for the RAS was developed, whereby the effective design window and the lower and upper limits were determined.

The reflection losses of the nano-composites were calculated using the commercially available software package MATLAB R2013a (MathWorks Inc., USA) and the variations in the EM wave absorbing characteristics were investigated with respect to the dielectric properties of the nano-composites.

In this study, a theoretical method for determining the EM wave absorbing characteristics of the nano-composite RAS was developed in the X-band frequency range (8.2вЂ“12.4В GHz). Since the EM wave absorptance of the RAS is highly dependent on the dielectric property of the nano-composite, the optimum design method should be established considering both the dielectric property of the nano-composite and the EM wave absorbing characteristics of the RAS. The carbonaceous conductive particles improve the EM wave absorbing characteristics of the RAS,. The RAS usually consists of a nano-composite composed of an E-glass/epoxy composite dispersed with carbonaceous conductive particles and a perfect electric conductor (PEC), as shown in Fig. Among these methods, the RAS is most effective as a result of both its load bearing and EM wave absorbing capabilities. The second area is the shaping targets, applying radar absorbing materials (RAMs) and a radar absorbing structure (RAS) to the body of the weapon system, ,. Recently, hybrid composites composed of both E-glass/epoxy and aramid/epoxy composites were adopted in low-observable radomes. Low-observable radomes were usually composed of either E-glass/epoxy or aramid/epoxy composites. The low-observable radome has an electromagnetic (EM) wave selectivity function whereby the EM wave of in-band frequency transmits to the radome structure, while the EM wave of out-of-band is reflected by the radome structure. The first area is the low-observable radome that is applied to the radar antenna system of the weapon system. In radar stealth technology, there are two major research areas with respect to the positions on the weapon systems where the stealth technologies are applied. Therefore, the reduction in the RCS of the weapon system is an important topic in the field of stealth technology. The RCS is the power reflected or scattered by a radar target, which is the product of an effective area and a power density whose direction is back toward the radar. The possibility for a weapon system to be detected by a radar antenna is determined by the radar cross section (RCS) of the weapon system. Stealth technology makes a weapon system less visible to detection systems such as radar antennae of adversaries. Stealth technology which is essential for national defense technologies, increases not only the survivability of a weapon system but also the operational performances in warfare. Then the RAS was constructed with the nano-composite composed of an E-glass/epoxy composite and carbon black and its EM wave absorbing performances were measured and compared to those obtained through theoretical calculations and numerical simulations. Based on the theoretical investigation, an optimum design method for the RAS was developed. In this study, a theoretical method for the EM wave absorbing characteristics of nano-composite RAS was developed with respect to the dielectric properties of the nano-composites. Therefore, an optimum design method for RAS considering the dielectric properties and the EM wave absorbing characteristics should be established. The EM wave absorptance of the RAS is highly dependent on the dielectric properties of the nano-composite. A radar absorbing structure (RAS) is generally constructed using nano-composites composed of an E-glass/epoxy composite dispersed with carbonaceous conductive particles to improve the electromagnetic (EM) wave absorbing performance.
