- Abstract
- Telecommunication systems use advanced signal processing techniques based on multiple band operation/access, implying that frequency-selective EMI shielding solutions are preferred to classical broadband absorption. Mathematical considerations show that an arrangement of successive dielectric and conductive layers stands out as an attractive solution. A smart multilayer arrangement of polymer and carbon nanotubes produces an absorber where transmitted and blocked wavelengths can be controlled. The conductive layers are stacked in gradient of conductivity in order to limit the reflection of incident microwave and so increase absorption index. Thickness and permittivity of the dielectric polymer open up narrow transmission windows in the spectrum. It is therefore possible to isolate a room or building from a wide range of telecommunication systems except for narrow bands using a material with a total thickness lower than .
