Abstract
A composite dielectric in which particles having a volume resistivity of between 2 ohms-cm and 2 mega-ohms-cm are dispersed. This composite dielectric is much more dissipative for electromagnetic fields in the microwave-frequency region than a conventional one wherein highly-conductive particles are dispersed.
