Abstract :
A novel method is developed to derive the surface ray geometric parameters required in the high-frequency computations of antenna characteristics for radiators located on an aircraft wing modeled by finite sections of a general parabolic cylinder (GPCYL) and right circular cylinder. This hybrid quadric cylinder (h-QUACYL) is treated by the geodesic constant method (GCM) which expresses all the surface ray geometric parameters in terms of the first geodesic constant, which can be determined in closed form. Results are presented for wings designed for different flight regimes.<>
