In order to study the effect of the antiresonant core-surround ring interface on the confinement loss and scatter loss, the given hollow-core photonic crystal fibers(HC-PCFs) with different antiresonant core-surround rings and core radius were simulated by means of full-vector finite element method, and the curves among the effective index, confinement loss and power-percentage in core with change of wavelength were obtained. The numerical simulation shows that, when the antiresonant core-surround ring is designed as T=3 annular or elliptic geometry, the confinement loss reduces 2 order of magnitude and the power-percentage in core increases 13% in communication wave band which demonstrate both the designs in this paper can reduce the confinement loss and scatter loss in HC-PCFs effectively.
