摘要: Maxwell fisheye lens was proposed to pinpoint super-resolution with the
addition of 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
full-wave simulation that coupling nature for wave source and drain applies
correctly in the picture of scanning imaging for absolute instrument. This work
prospects for scanning near fields shaped from far-field wave propagation.
