Developing a New Method to Control Electromagnetic Compatibility

Engineers from the St. Petersburg Electrotechnical University “LETI” have created a new dynamic way to control electromagnetic compatibility. The technique relies on using common radiation-absorbent fillers to create a new composite, which is based on conductive polymer polyaniline.

Researchers happened on the compelling idea of using a dielectric polymeric composite film made of gelatin as part of their design. This film contains distributed absorbing electromagnetic radiation particles.

Unlike other methods used to achieve electromagnetic compatibility, this technique can grant even a small thickness of a material a high coefficient of absorption of electromagnetic radiation. This radiation is well in the range of frequencies found in household sources of electromagnetic interference.
