Abstract

We introduce a loss compensation method to increase the resolution of\nnear-field imaging with a plasmonic superlens that relies on the convolution of\na high spatial frequency passband function with the object. Implementation with\nincoherent light removes the need for phase information. The method is\ndescribed theoretically and numerical imaging results with artificial noise are\npresented, which display enhanced resolution of a few tens of nanometers, or\naround one-fifteenth of the free space wavelength. A physical implementation of\nthe method is designed and simulated to provide a proof-of-principle, and steps\ntoward experimental implementation are discussed.\n
