Paper Abstract

The I-V characteristics of stacked Nb/(Al/A1Ox/Nb)n superconducting tunnel structures with n=3 and n=6 were measuredunder microwave irradiation of 45 and 136 GHz. The classical responce of the structures was observed over a wide range ofinput RF power at 45 GHz. Photon-assisted steps in the I-V characteristics were observed at 136 GHz. The widths of the stepscorrespond to the response from only 2 and 4 junctions in 3- and 6-barrier structures, respectively.
