Computer-aided design-based high-frequency electromagnetic wave scattering from complex bodies

This work investigates the use of high frequency electromagnetic scattering techniques, such as the physical theory of diffraction (PTD) and the geometrical theory of diffraction (GTD) and the shooting and bouncing rays (SBR) method combined with computer aided design (CAD) compatible geometries, to perform the electromagnetic scattering analysis of complex arbitrary bodies. The use of CAD formats such as solid modelled bodies and bodies modelled with triangular patch surface elements allows the scattering analysis of arbitrary bodies which can be constructed using CAD packages. The scattering analyses are applied to radar cross section (RCS) problems, cavity radiation problems, and antenna pattern predictions of complex electrically large structures, thereby showing that it is feasible to accurately approximate the electromagnetic wave scattering from general complex bodies using CAD techniques and high frequency scattering techniques.
