Self-replicating energy blindfold matrix

From Tardis Wiki, the free Doctor Who reference

A self-replicating energy blindfold matrix was the result of macrotransmission of a K-filter wavelength. This had the effect of blocking all the Dalek weaponry. In 2009, one was produced by the DoctorDonna's use of Crucible's control console during the Dalek Invasion of Earth. (TV: Journey's End)
