You are 100% correct Bert! An easy way to determine the relative 
losses in a dialectric due to R.F. absorbtion is to look a the power 
factor for that dialectric, the smaller the power factor the smaller 
the amount of R.F absorbed and consequentialy the less the dialectric 
will heat up in operation.
