RFS Consultancy is run by Robert Sims BSc FIMMM. Straight from Edinburgh University, Robbie started with Marconi Wireless Telegraph Co at their Research Centre in Great Baddow, Essex. The group were developing and researching microwave ceramic materials both magnetic and dielectric. Over the ensuing years this group went on to become a world source for a vast range of Microwave Ferrites and Dielectric Ceramics, Rare Earth Garnets, both polycrystalline and single crystal as well as spinels and other forms.

These materials were used by the group to produce a comprehensive range of microwave components including circulators, isolators, terminations in waveguide and co-axial configurations at frequency ranges from 100 MHz to 100 GHz and power levels up to 100+ KW.

Robbie finished at GEC Marconi Lincoln as Chief Engineer Materials Group in 1994. At this time the materials work was deemed no longer core business, so he participated in a management buy-out of the materials technology resulting in the set up of Hiltek Microwave based in Sittingbourne where he was Director of Engineering.

Robbie left Hiltek in 1997 to form RFS Consultancy and continued to provide a consultancy service to Hiltek for several years. During this time with Hiltek he completed a Transfer of the Materials Technology to establish the Advanced Materials Group facility in Calcutta for the Associated Cement Companies, part of the Tata Group.

Subsequently he was involved with RT Circuits as Technical Director, and RT Microwave as MD and Chair. Work included trying to exploit some Brunel University patents to produce printed circuits by offset lithographic printing processes. Since then he has been providing a sourcing and sales service mainly to UK and French customers for materials and microwave components.
