This paper presents most properties of radiation from a tapered Apple-II undulator. The study demonstrates that tapering an Apple-II undulator can broaden the harmonic bandwidth and the performance of polarization is also excellent at the broadened energy range. So Apple-II undulator can be tapered to provide more convenience for energy scan experiment.
