We know that conductive polymers like Polypyrrole can be used for radar absorbent materials,but what is the exact relation between conductivity of them and radar absorption?
After posting this question I saw this paper.it really helped a lot.So I am uploading it.
In addition to this, you'll find in my RG profile a few papers about microwave and THz applications of carbon foams. Electrical conductivity is indeed needed, so either foams can be coated by an insulating layer (such as in your paper), or be intrinsically conductive (in my case).

Dear Mr. Biswas.
a polymer have different EMC characteristics absorption this is eps ´´ (f) and relative
conductivity ´´ (f) . Also the characteristic is not only 100 % absorption, so we have any percent refection.

Dear Mr. Biswas.
a conductive polymer absorb of course the HF field. Why ? If the conductivity
is perfect to 100 % , so we have only the reflection effect. But the conductive effect in a conductive polymer is not perfect and not 100 %. So we have the dielectric loss with the value eps ´´(f) and this value give us the degree of the absorption, also with the complex part of the conductivity. Magnetic effect is zero I hope.
All the best
