Semantics… ha ha ha… NO !
I’ll try to explain things to you so stick with me please.
Yes, It is possible for a material to absorb energy. But the keys to doing this are a function of the EMF frequency corresponding to the electrical size of the object.
So for your understanding, the way that works is, and I am heavily simplifying, IF the material thickness is any multiple of 1/4 of the frequency wavelength of the EMF wave, a reduction of the signal energy is possible. => Your actually combining the phase components of the signal vibrating around inside the medium or metal which are 180deg out of phase with each other so the signal cancels itself …and this you can call absorption.
On the other hand, if instead the EMF frequency wavelength is half the material thickness, the phase of the signal resonates and gets louder (tuning fork analogy where the phases of the waves are at the same place and combine to amplify the energy instead of cancel).
Now this is important, keep in mind that the energy which is not absorbed is scattered off of the material depending on the fresnel properties of that material, both away, AND INSIDE YOUR VEHICLE. Your material is also an antenna and scatters the excess energy in ALL directions.
This behavior in the standing wave realm is not that of a ball that always bounces off a building wall. But your shielding metal can actually work as a transmitting mechanism to the inside of your vehicle and you have hosed yourself.
Your posts sound like you think the wave behavior is no different from a ball bouncing off a wall. That is where your understanding is hung up. =>Things are not this way in the standing wave realm of physics.
