Sidelobe Modification for an Offset Gregorian Reflector System using a Reconfigurable Intelligent Surface-Equipped Subreflector

This article likely presents a novel approach to improve the performance of reflector antenna systems. The use of a Reconfigurable Intelligent Surface (RIS) on the subreflector suggests an attempt to dynamically control the antenna's radiation pattern, specifically targeting sidelobe reduction. The offset Gregorian configuration is a well-established antenna design, and the research likely focuses on enhancing its performance through RIS technology.
