EMI shielding sheets films rfid absorber
l to have a certain thickness, only the discontinuity at the interface.
The energy that is not reflected by the surface and enters the shielding body is attenuated by the shielding material during the forward propagation in the body. Also known as absorption.
When the residual energy that has not been attenuated in the shield body is transmitted to the other surface of the material, it encounters the interface with discontinuous metl-air impedance, which will form a re-reflection and ret
