Abstract :
A new ray-tracing method has been developed for the analysis of antennas on-board complex structures and to compute the propagation at indoor/outdoor environments considering n-bounces. The structures (satellites, ships, aircrafts, etc.) are modeled by planar and/or curved surfaces defined by perfectly electrical conductors or dielectric materials (with or without losses). The structures are defined as parametric surfaces, in particular by NURBS (Non-Uniform Rational B-Spline) surfaces. The approach is based on the Uniform Theory of Diffraction (UTD) for the field computation.
