concrete dielectric constant and loss - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Greetings chirag:

I did a seach on Yahoo for "dielectric constant concrete" and got this research paper from the University of Vermont (my alma matter, coincidently) in the #1 position. I did not do a lot of scanning through it, but it looks like a lot of useful info in there. You need to make sure steel reinforcement bar matrices are included in your attenuation calculation.
