Real-time analysis of the telegrapher's equation for tunneling processes.
Based on a close analogy with an RLC circuit, a model for interpreting delay times in forbidden regimes (tunneling) is formulated, avoiding the analytical continuation into imaginary time. In this way, a reasonable description of experimental data, which were previously reported for a waveguide propagation below the cutoff frequency at approximately 9.5 GHz, is obtained.
