This paper presents two methods related to modelling of reflector antenna struts and surrounding structural features such as satellite platforms. One method is a MoM-based strut model and represents an improvement of an existing PO-based model, thus enabling analysis of…

This paper describes the pattern computations of the UHF antennas mounted on the spacecraft of the EXOMARS mission. The analyses are made by the higher-order Method of Moments (MoM) add-on to GRASP and are computed twice. In the first computation,…

An efficient Body of Revolution Method of Moments formulation is presented in which the unknown surface current density on the generatrix of the rotationally symmetric scatterer is expanded in terms of higher-order hierarchical Legendre basis functions. Careful attention has been…

Two different antenna models are set up in GRASP and CHAMP, and noise is added to the radiated field. The noisy field is then given as input to the 3D reconstruction of DIATOOL and the SWE coefficients and the far-field…

Reverberation chambers (RCs) are important measurement facilities, and thus it is often required to simulate their behaviour numerically. However, due to their special characteristics, especially for high Q factors, they are often considered too challenging for application of standard numerical…
