Purpose and goal
Nowadays, most of the National metrology institute (NMIs) around the world can provide traceable measurements up to 110 GHz. Moreover, NIST, PTB and NPL can even provide precise and traceable measurements above 110 GHz. Currently, PTB research is focused on the extension of traceable power and S-parameter measurements above 110 GHz. PTB has also share with SP the interest in performing bilateral measurements comparisons at 110 GHz and above. This project contains a study of the need for developing THz metrology at SP/RISE.
Expected results and effects
The frequency regions where further development of traceable metrology is requested is mainly sub 100 GHz. This is where vehicular radars operate, as well as microwave communication in fixed terrestrial microwave links as well as satellite communication. Need for traceable references above 100 GHz includes sensors for Space applications and atmospheric observation, and terrestrial communication links. Within this project RISE/SP has studied the possible the setup solution and the expected uncertainty for such measurements.
Planned approach and implementation
The Swedish microwave industry is robust and advanced, and the companies working with sensors, satellite communication and space applications are successful. A request for accurate and reliable measurements at above 1 THz comes from academic research at universities, mainly Chalmers. Within the GHz Centre project, SP/RISE has performed preliminary measurements of devices up to 1.1 THz. Precise and accurate measurements at THz frequency will enable Chalmers to develop high frequency model that can be used to predict device performances operating at THz frequency.
