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.

Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
