We investigate the use of alkali atoms as electric field sensors for high frequency on wafer measurements These atoms are well defined quantum systems and hold a promising potential for accurate and traceable measurements The project aims to map electric fields above a coplanar waveguide and to determine microwave power and S Parameters up to 50 GHz.

The project (23IND10 OnMicro) has received funding from the European Partnership on Metrology, co-financed from the European Union’s Horizon Europe Research and Innovation Programme and by the Participating States.
