Due to the ability to reshape the wireless communication environment in a cost- and energy-efficient manner, the reconfigurable intelligent surface (RIS) has garnered substantial attention. However, the explicit power consumption model of RIS and measurement validation, have received far too little attention. Therefore, in this work, we propose the RIS power consumption model and implement the practical measurement validation with various RISs. Measurement results illustrate the generality and accuracy of the proposed model. Firstly, we verify that RIS has static power consumption, and present the experiment results. Secondly, we confirm that the dynamic power consumption of the varactor-diode based RIS is almost negligible. Finally but significantly, we model the quantitative relationship between the dynamic power consumption of the PIN-diode based RIS and the polarization mode, controllable bit resolution, working status of RIS, which is validated by practical experimental results.
