Universal Relationship of Tunnelling Time and Frequency — •Günter Nimtz and Astrid Haibel — Universität zu Köln, II. Physikalisches Institut, Zülpicher Str. 77, 50937 Köln

Various photonic tunnelling time experiments have been carried out using electromagnetic radiation both at microwave and optical frequencies. We have carefully analyzed our own experimental results and those of others and have found that in all such experiments the tunnelling transit time is approximately equal to the reciprocal (1/f) of the corresponding frequency of radiation independent of the type or shape of the actual barrier. As a result of the mathematical equivalence between photonic and wave mechanic tunnelling we conjecture that this universal relationship holds for all tunnelling processes.
