Five canonical QO components are discussed, namely parabolic reflectors, elliptical lenses, hemispherical lenses, hyperbolic lenses, and elliptical mirrors. The ray tracing technique is implemented to describe reception scenarios and visualize the phase aberrations in the QO systems. The FO method represents the fields focalized by a QO component on its focal plane as a Plane Wave Spectrum (PWS). This spectrum is calculated by using the GO method and can be used in spectral techniques like equivalent Floquet circuit. Moreover, the tool is able to use this spectrum to estimate the power delivered to an antenna placed at the focal plane. By obtaining this delivered power, the performance of the antenna-coupled QO system is analyzed, including pattern, directivity, common efficiency terms, and gain. In addition, the performance calculated in reception is validated by CST and GRASP full-wave simulation software. Therefore, this GUI tool represents a GO/FO based tool that can be used to analyze and design antenna-coupled QO systems in reception.
