Implementation of Refined Ray Tracing inside a Space Module

摘要

Modern space modules are susceptible to EM radiationudfrom both external and internal sources within the spaceudmodule. Since the EM waves for various operations areudfrequently in the high-frequency domain, asymptotic raytheoreticudmethods are often the most optimal choice foruddeterministic EM field analysis. In this work, surfaceudmodeling of a typical manned space module is done byudhybridizing a finite segment of right circular cylinder anduda general paraboloid of revolution (GPOR) frustum. Audtransmitting source is placed inside the space module andudtest rays are launched from the transmitter. The rays areudallowed to propagate inside the cavity. Unlike theudavailable ray-tracing package, that use numerical searchudmethods, a quasi-analytical ray-propagation model isuddeveloped to obtain the ray-path details inside the cavityudwhich involves the ray-launching, ray-bunching, and anudadaptive cube for ray-reception.
