摘要
We report on a large sharp variation (∼103 times) of the quality-factor of a quasioptical dielectric resonator with conducting endplates in the form of ultra-thin copper films as their thickness changes only to ∼0.9 nm. The measurements have been carried out in the 8-mm waveband at room temperature. An explanation of the effect is represented based on both the microwave properties of the resonator with a film and the dependence of continuity of ultra-thin copper films on the thickness. © 2006 Begell House, Inc.
