Claim 21:
22. The method as defined in claim 18, further involving testing or tuning the performance of the wireless power transmitter device when determining a (reference) quality factor of a wireless power transmitter coil thereof under the influence of a wireless power receiver coil of a wireless power receiver, the (reference) quality factor being defined as a ratio between reactance and resistance of the wireless power transmitter coil, by:
causing said manipulation of the electromagnetic signals exchanged between the wireless power transmitter and receiver devices by adding pieces of conductive material to a planar non-conductive base sheet of the probe device; and
varying at least one property of the pieces of conductive material, thereby causing a controlled change in the (reference) quality factor observed by the wireless power transmitter device between a first (reference) quality factor and a second (reference) quality factor, said second (reference) quality factor being lower than said first (reference) quality factor.
