electrical properties of several materials at L-band

Hello,

I am in search for the electrical properties (permittivity and permeability) at L-band of several materials such as, but not limited to:
-various soil constitutions and humidity
-construction materials (glass, concrete, reinforced concrete...)
-natural obstacles such as trees

Does anyone know good references listing the electrical properties of these materials?

Thank you.
Best regards.

I have had similar problems running down electrical parameters of construction materials.

Try the material manufactures and trade associations. I had some success with the Portland Cement Association and found someone there who understood the question.

Just start digging. It is time consuming and maybe you will get lucky and find someone who has compiled a list. You might also look into the IEEE archives for articles that are similar to your application. that is another place to look for electrical parameter information.
