Composite Materials

Advanced Helicopter Electromagnetics Laboratory | Comments

The effort in the area of Composite Materials is focused on modeling non-metallic materials. The Green's function approach coupled with distributed surface impedance concept has been used as a preprocessor for the NEC code to model low-conductivity helicopter panels. In addition, more rigorous modeling techniques, such as the FDTD method, have been developed and applied. More specifically, a 3D automatic volumetric FDTD mesh generator has been developed for modeling thick and volumetric dielectrics by using the FDTD method. The 3D mesh generation, plus the FDTD solver, makes it possible to model antenna elements mounted on composite structures. Research in this area also includes the problems of material parameter measurements, antenna pattern control via material loadings, and electrical fields penetration through composite panels of a helicopter.
