Attenuation and phase constants of Concrete wall?

[Guest wuming79]

Does anyone knows what is the EM attenuation constant and phase constant of the concrete wall?

 

Or does anyone knows the loss tangent, the permitivity and the permeablity of the concrete wall from the range of 2 GHz to say 10 GHz??

it isn`t or rather could never be a "Constant" as it would depend on agregates and density.

what mix are you asking about?

1:2:4 mix?

High strength?

lightweight (relative to binder content)?

does it have rebar in it?

it need more data as you can see

 

but for absorbtion and ignoring the Compton effect, it averages at about 2.35 p/g cm^-3 E/MeV

thats running at X-ray and Gamma Ray potentials.

 

hope that helps a little???

oh.. I'm not very sure of all the details...I am currently trying to do a simulation of passing an UltraWide Band waveform through a concrete wall using matlab. I read from some of the articles that they can calculate the attenuation of the wall with pemeability and permitivity but it did not give an values to it so I thought if I could get a range of values maybe I can get my characterized wall.

 

Can u provide me some values of different types of wall? Some common types of wall will do.
