外文摘要：In this paper, we propose a novel method for high-frequency and semi-infinite Bessel integrals. We decompose the integration interval into a finite part and a tail part. Each component is then efficiently approximated using numerical steepest descent method. Theoretical analysis and numerical examples are presented to show its efficiency.
