Through exploring the relationship between the Q-factor and the normalized electric field strength of a reverberation chamber, this contribution proposes a new kind of methods for the Q-factor estimation, which can simplify the procedure of measuring Q-factor in experiment and raise the e±ciency of calculating Q-factor by simulation. Firstly, the method is validated using measured electric field, then it is verified using data from RC's simulation by FDTD. Satisfactory agreements confirm this kind of methods could act as a reliable tool in evaluating Q-factor by both experimental measurement and numerical simulation.
