Abstract

The electromagnetic properties of artificial molecules composed of small linearly loaded antennas embedded in a host medium are derived and discussed. It is demonstrated that the electromagnetic characteristics of these artificial materials can be designed by carefully selecting their loads. Various previously known material models (Debye, Lorentz) are recovered and their properties are generalized to more complex behaviors (Time Derivative Debye and Lorentz). Inherent duality between the dielectric and magnetic molecules allows us to derive a matched material satisfying ∈r =μr over broad frequency bandwidths. The electromagnetic properties of bianisotropic molecules composed of two antennas in tandem are presented. The electromagnetic characteristics of composite materials derived from these bianisotropic molecules are derived through an application of the Maxwell-Garnett Law.
