    "abstract": "Some recent theoretical studies have tended to employ analytically-continuous\n{\\em gaussian}, or infinite-bandwidth step pulses to examine tunneling process.\nThe stationary phase method is often employed to this aim. However, {\\em\ngaussian} functions do not have a well-defined front, such that their speed of\npropagation becomes ambiguous. Also, infinite bandwidth signals cannot\npropagate through any real physical medium (whose transfer function is\ntherefore finite) without pulse distortion, which also leads to ambiguities in\ndetermining propagation velocity during the tunneling process. In this\nmanuscript, we appoint some incompatibilities with the application of the\nmethod of stationary phase in deriving tunneling times which, eventually, can\nruin the {\\em superluminal} interpretation of transition times.",
