دامنه ی این که مدل های انتگرال مسیر، برای امواج خلایی (تونل زنی) و پیچیده (نزدیک زمین) است

The usefulness of a stochastic approach in determining time scales in tunneling processes (mainly, but not only, in the microwave range) is reconsidered and compared with a different approach to these kinds of processes, based on Feynman’s transition elements. This latter method is found to be particularly suitable for interpreting situations in the near field, as results from some experimental cases considered here.
