Abstract

This paper presents the work of the LAPLACE Electromagnetism Research Group to build an experimental setup able to measure tiny forces that may appear in microwave cavities, in the context of EMDrive investigations. It is based on a commercial balance in the range of 0.1 mN sensitivity, a contactless feeding for more than 150~W RF power, and self calibrating device process. It requires a double cavity system in mirror configuration and is here experimented with frustum cavities, different from the NASA one [1]. The global setup can make force measurement and calibration in less than two seconds. Investigating two different cavities and various electromagnetic modes for the biggest, no force is reported while the 0.1 mN sensitivity is demonstrated.
