Abstract


An analysis of the super-resolution properties of the Maxwell Fish Eye (MFE) has been done using an equivalent device known as Spherical Geodesic Waveguide (SGW). A microwave circuit comprising three elements: the SGW, the source and the drain (two coaxial probes) is designed and simulated in COMSOL. The super-resolution properties are analyzed using Scattering parameters of the microwave circuit for different position of the source and drain. The drain port is loaded with impedance Zd, which is properly calculated to act as the perfect drain, i.e. the incident wave is absorbed with no reflection or scattering.
