“…These devices have the great potential for near-field super-resolution microscopy. In addition, SPs can also be employed in far-field microscopic imaging mode, such as standing wave surface plasmon resonance fluorescence microscopy (SW-SPRF) 11 12 13 and structured illumination microscopy (SIM) 14 15 . In these two methods, standing SPs wave patterns are used as the illumination patterns.…”

A gradient permittivity meta-structure (GPMS) model and its application in super-resolution imaging were proposed and discussed in this work. The proposed GPMS consists of alternate metallic and dielectric films with a gradient permittivity which can support surface plasmons (SPs) standing wave interference patterns with a super resolution. By employing the rigorous numerical FDTD simulation method, the GPMS was carefully simulated to find that the period of the SPs interference pattern is only 84 nm for a 532 nm incident light. Furthermore, the potential application of the GPMS for wide-field super-resolution imaging was also discussed and the simulation results show that an imaging resolution of sub−45 nm can be achieved based on the plasmonic structure illumination microscopic method, which means a 5.3-fold improvement on resolution has been achieved in comparison with conventional epifluorescence microscopy. Moreover, besides the super-resolution imaging application, the proposed GPMS model can also be applied for nanolithography and other areas where super resolution patterns are needed.

“…Furthermore, the deep-subwavelength SPP probes can also be dynamically tailored to phase shift as the excitation pro¯les of super-resolution wide-¯eld°uorescence imaging. 12,13 The pro¯le gives a 2D lateral resolution enhancement in wide-¯eld high-resolution°uorescence imaging. Although a super-resolution imaging may be achieved with wellknown stimulated emission depletion (STED), 14 photoactivated localization microscopy (PALM) 15 and stochastic optical reconstruction microscopy (STORM), 16 our approaches provide the possibility of highly compact, potentially integrated architectures within much smaller volumes.…”

“…Existing SPP excitation methods include prism coupling, grating coupling, edge/slit coupling, objective coupling, and near-field excitation. [212] Among these methods, grating coupling, [255] edge/slit coupling, [103] and objective coupling excitation [256][257][258] are mostly used in PSIM configuration for their convenience in implementation and possibility of generating regular SPP interference patterns, which is superior to irregular ones in terms of resolution and signal-to-noise improvement in the imaging. [259] The implement of PSIM requires illumination patterns to be tuned with multiple directions and multiple phase shifts.…”

The diffraction limit substantially impedes the resolution of the conventional optical microscope. Under traditional illumination, the high-spatial-frequency light corresponding to the subwavelength information of objects is located in the near-field in the form of evanescent waves, and thus not detectable by conventional far-field objectives. Recent advances in nanomaterials and metamaterials provide new approaches to break this limitation by utilizing large-wavevector evanescent waves. Here, a comprehensive review of this emerging and fast-growing field is presented. The current superresolution imaging techniques based on evanescent-wave-assisted spatial frequency modulation, including hyperlens, microsphere lens, and evanescent field-illuminated spatial frequency shift microscopy, are illustrated. They are promising in investigating unobserved details and processes in fields such as medicine, biology, and material research. Some current challenges and future possibilities of these superresolution methods are also discussed.
