Although superresolution can be successfully obtained by negative index materials, the unavoidable losses ultimately limits image resolution. Using the near-field active phase-correction method, we theoretically predict the significant enhancement of both superresolution and transmission in a realistic lossy superlens system. In a SiC superlens system, resolvable separation between two slits significantly improves from λ/4.2 to λ/14.2 and the transmission increases 30.5 times compared to the conventional index match method.
