Abstract

A composite oligomeric material includes one or more repeating backbone units. One or more polarizable units are incorporated into or connected to one or more of the one or more repeating backbone units. One or more resistive tails are connected to one or more of the repeating backbone units or to the one or more polarizable units as a side chain on the polarizable unit. The composite oligomer material may be polymerized to form a metadielectric, which may be sandwiched between to electrodes to form a metacapacitor.
