High-Performance Processing with Equivalent Currents: Results on a Very Large Measured Antenna

The method of the equivalent currents for antenna diagnostics has been widely demonstrated over the years on a large set of measured data. Its key advantage is to provide a complete 3D representation of the antenna by a direct post processing, without any additional testing, like probing. Recently, the method has been equipped by a technique based on a Nested Skeletonization Scheme (NSS) for post processing of very large antennas. In a previous investigation the post-processing with NSS has been applied to a prototype of an array antenna. Only a portion of the array geometry has been considered in the investigation for the limitation imposed by RAM constraint. In this paper we will show a new technique that enhances the NSS method for processing of large problems and that makes possible a complete diagnostics investigation where previously this was not feasible.
