Abstract :
The unloaded quality factor of resonators whether coupled magnetically or electrically, with loss or without loss, is estimated by the critical points (i.e., extreme-reactance/susceptance points) method. The critical-points method derived from this paper is a fast and accurate method for unloaded Q measurement and is suitable for general external coupling environment
