Super-resolution imaging involves the interaction of electromagnetic waves with objects that have dimensions similar to, or smaller than the wavelength. That is precisely the hallmark of microwave technology. It suggests that microwave concepts and design approaches may be helpful not only in the description and modeling of the superlens behavior, but can provide useful tools for designing and realizing the superlens, notably the metamaterial itself. In this paper we present some interesting results and insights yielded by the microwave perspective, including waveguide, circuit and filter representations of the superlens.
