    "abstract": "Time-dependent analytical solutions to Schr\\\"{o}dinger\u0027s equation with\nquantum shutter initial conditions are used to investigate the issue of the\ntunneling time of forerunners in rectangular potential barriers. By using a\ntime-frequency analysis, we find the existence of a regime characterized by the\nopacity of the barrier, where the maximum peak of a forerunner measured at the\nbarrier transmission edge $x=L$ corresponds to a genuine tunneling process. The\ncorresponding time scale represents the tunneling time of the forerunner\nthrough the classically forbidden region.",
