Cutting-edge nanophotonic systems are increasingly displaying a magnetic, as well as an electric optical response that, for example, is integral to phenomena such as negative-index of refraction [1]. For these applications, and for many others such as those based on extraordinary optical transmission [2], the details of the response are important. For example, for negative index metamaterials the spectral location of the magnetic and electric resonances determines the window in which the material has n |
