Abstract
Both explicit analysis and FEM numerical simulation are used to analyze the fleld distribution of a line current in the so-called Maxwell's flsh eye lens (bounded with a perfectly electrical conductor (PEC) boundary). We show that such a 2D Maxwell's flsh eye lens cannot give perfect imaging due to the fact that high order modes of the object fleld can hardly reach the image point in Maxwell's flsh eye lens. If only zeroth order mode is excited, a good image of a sharp object may be achieved in some cases, however, its spot-size is larger than the spot size of the initial object fleld. The image resolution is determined by the fleld spot size of the image corresponding to the zeroth order component of the object fleld. Our explicit analysis consists very well with the FEM results for a flsh eye lens. Time-domain simulation is also given to verify our conclusion. Multi-point images for a single object point are also demonstrated.
