Abstract

We present a simple and accurate . ethod for the analysis of tunneling through an arbitrary onediaensional potential barrier based on the Modified Airy Function approach. We have considered truncated step-linear parabolic and quartic potential barriers. The results have been coipared with those obtained by the conventional WKBJ modified WKBJ and the aatrix sethod. The effect of the truncation level on the tunneling coefficient has also been investigated. I .
