Complex Microwave Conductivity of Na-DNA Powders
Complex Microwave Conductivity of Na-DNA Powders
We report the complex microwave conductivity, σ=σ 1 -iσ 2 , of Na-DNA powders, which was measured from 80 to 300 K by using a microwave cavity perturbation technique. We found that the magnitude of σ 1 near room temperature was much larger than the contribution of the surrounding water …
