3 patents have been applied for & one has been sold to Airbus. 56 journal articles & conference papers have been published to June 23 with more in pipeline. The project has engaged with the public via a family moon base workshop, its website, linkedin, twitter, radio, other media outlets & open days at schools & universities. Progress beyond the state of the art includes 1.Developed designs of reconfigurable waveguide transitions & reconfigurable Linear-polarized/left-handed circular-polarized/right-handed circular-polarized waveguide antenna arrays to provide wideband performance & flexible functions in a beamforming system for satellite communication applications 2.An extremely compact miniaturized filter based on substrate integrated waveguide technology (SIW) has been designed, manufactured, tested & published at 2021 IEEE MTT-S International microwave filter workshop 3.Various tunable devices with minimal deterioration of high-Q frequency-selective performance have been researched, developed & characterized 4.Designed & fabricated a reconfigurable radar antenna frontend using a novel switching circuit 5.Utilisation of ceramic material as an efficient resonator in filters suitable for satellite technology results published in IEEE access 6.Designed several filters of different orders using waveguide & substrate integrated waveguide (SIW) technology, with wide stopband rejection performance for narrow & wideband applications results published in IEEE Transactions on Microwave Theory & Techniques 7.Developed several filters using various additive manufacturing technologies with new filter topologies & geometries achieving highly efficient filtering responses, including transmission zeros, resulting in selective responses & low losses 8.Pushed the boundaries of current manufacturing techniques to achieve non-planar passive components for MW with improved characteristics (wider spurious rejection, miniaturization, easy assembly, flexible manufacturing) 9.Several prototypes of smooth-profiled low-pass filtering structures, operating in different frequency ranges, have been produced using metal additive fabrication techniques 10.Several components (such as combline filters & rectangular waveguide diplexers) showing wide tuning ranges (for centre frequency & bandwidth) have been successfully demonstrated using novel tuners based on dielectric materials 11. Ceramic materials based on aluminium-nitride composites have been investigated, in terms of properties (loss tangent, thermal conductivity) & sintering methods. 12.Developments for millimetre hardware for next generation of satellite communications have been proposed in 10 journal articles13.Developed high-performance silicon micromachined components for satellite applications in THz frequencies 14.Developed several concepts of metamaterial or metasurface filters for both reconfigurability & out-of-band rejection improvement of components 15.Developed topology optimization tools to produce miniaturized components, filled of dielectric material like specifically engineered ceramics, using additive manufacturing techniques for novel high power components. Overall this has developed European Space capability through developing payload flexibility, internet of space technology, high speed communication and remote sensing and high power technology & by training 15 ESRs keen to continue working in this area. The 4.5 year project established strong links between partners (academic & industry) & with other Space related projects providing for ongoing opportunities for the research work started in TESLA.
