Abstract
Experimental results on the optical conductivity of thin films of high -T-c superconductors show additional absorption at low FIR frequencies . We show by explicit calculations that this absorption can be explain ed by a model of random Josephson barriers. In this model the absorpti on is caused by the strong fields inside the barriers set up by the ac cumulated charges at the junction boundaries.
