Abstract
The Maxwell fish-eye lens was proposed to reach super-resolution with the addition of a wave drain, and the interaction of multiple drains is theoretically predicted to improve subwavelength resolution further. In this paper, we discuss the role played by port drains in optical absolute instruments and verify by wave simulation that the coupling nature for the wave source and drain applies correctly in the picture of scanning imaging for an absolute instrument. This work has prospects for scanning near fields shaped from far-field wave propagation.
