1. I have plotted log ac conductivity vs log frequency to find out power factor, S. I am getting S values (ie, slope of graph) below 1 for some samples and S values (ie, slope of graph) above 1 for some samples. wheather it is possible to get S values above 1. what may be the meaning?

2. set of sapmles with S values below 1 follows different trends. ie, in some cases S values are independent of temperature where as in some cases S values linearly increses with increase in temperature. Can anybody can explain?

(All the samples are bioplymer based composite containing conducting polymer as filler in low wt%)
