초록정보

 Electrical properties and RCS (Radar Cross Section) have been studied to predict stealth characteristics of composite plates. Reflection and transmission coefficients of composite materials were investigated by using one-dimensional finite element analysis. Permittivity and permeability of composite materials were obtained from S-parameters measuring. S-parameters were measured using the waveguide for 8.2~12.4GHz frequency range.  Glass/Epoxy fabric found to be suitable for transmission layer due to its low reflexibility and high permeability. Carbon/Epoxy fabric was shown to be proper to reflection layer due to its high reflexibility and high absorptivity. Two-layered structure that consists of Glass/Epoxy fabric and Carbon/Epoxy fabric makes reflection coefficient decrease.  RCS of composite plates were predicted by using PO (Physical Optics) method. PO method is a high-frequency approximation that gives best results for electrically large bodies. In this thesis, RCS of a rectangular plate of perfectly conducting material and composite plates were predicted using PO and compared with experiments.
