Abstract
Modern space modules are susceptible to EM radiation
from both external and internal sources within the space
module. Since the EM waves for various operations are
frequently in the high-frequency domain, asymptotic raytheoretic
methods are often the most optimal choice for
deterministic EM field analysis. In this work, surface
modeling of a typical manned space module is done by
hybridizing a finite segment of right circular cylinder and
a general paraboloid of revolution (GPOR) frustum. A
transmitting source is placed inside the space module and
test rays are launched from the transmitter. The rays are
allowed to propagate inside the cavity. Unlike the
available ray-tracing package, that use numerical search
methods, a quasi-analytical ray-propagation model is
developed to obtain the ray-path details inside the cavity
which involves the ray-launching, ray-bunching, and an
adaptive cube for ray-reception
