Abstract

The superlens with plasmonic material have important features such as evanescent wave enhancement and subwavelength imaging. However, the intrinsic loss of the material severely limits the resolution and imposes more stringent requirements on imaging conditions. In this work, we discuss the influence of different temporal features on imaging resolution. The exponential illumination corresponds to a definite imaging state, higher imaging resolution can be obtained with greater exponential decay rate of illumination pulse. This conclusion provides a reference for the selection of pulse time-domain waveforms. In addition, we use this method for periodic pattern imaging, validating its potential for practical applications.
