DOI: 10.1109/access.2021.3060398
Abstract: Convoluted elements on a frequency selective surface (FSS) allow for low frequency elements to be contained in physically smaller unit cells. Smaller unit cells give the FSS greater angular stability, especially where a curved FSS… read more here.

Dynamic modelling and control for fully-steerable large reflector antenna considering rigid-flexible coupling
Sign Up to like & getrecommendations! Published in 2017 at "Journal of Vibroengineering"
DOI: 10.21595/jve.2016.17438
Abstract: As the size of reflector antenna increases, the influence of flexible deformation to the system dynamics is much more significant. The coupling between the flexible deformation and the rigid displacement needs to be considered. However,… read more here.
