Verification of Generalized Far-Field Mode Filtering Based Reflection Suppression Through Computational Electromagnetic Simulation

A novel cylindrical mode-based measurement and post processing technique has recently been presented that allows data that has been acquired on a non-equally spaced abscissa to be processed rigorously. This technique was initially examined and validated using extensive, empirically derived data. However, the recent development of a digital-twin representation of a far-field antenna measurement system enables further and more detailed validation to be performed with results able to be assessed against a reliable “truth” model. This paper reports the results of that study presenting new analysis that further verifies the utility and flexibility of the very general error correction measurement and post-processing technique in configurations that hitherto have not been considered.
