High frequency electromagnetic energy phenomena in chiral dielectric structures with distributed and localized conductive insertions

Chiral dielectric structures with conductive insertions have the tendency to peculiarly concentrate the electromagnetic energy, subject to their specific architecture. The study analyses the associated heating effect at high transmission levels at GHz frequency, for the applications related to electromagnetic shielding. The favorable shielding structure can suffer, in well defined situations, a mechanical stress and/or an acceleration of aging mechanisms.
