Proximity correction and resolution enhancement of plasmonic lens lithography far beyond the near field diffraction limit
Near-field optical imaging methods have been suffering from the issue of a near field diffraction limit, i.e. imaging resolution and fidelity depend strongly on the distance away from objects, which occurs due to the great decay effect of evanescent waves. Recently, plasmonic cavity lens with off-axis light illumination was proposed as a method for going beyond the near field diffraction limit ...

This thesis provides a comprehensive study of the coupling phenomena that occur in plasmonic nanostructures. Electromagnetic coupling between metallic nanoparticles leads to strong spectral modifications in the structures, which are determined using linear optical spectroscopy in the visible and infrared wavelength range. In contrast to previous investigations, the key aspect here are the prope...
متن کاملFar-field super-resolution imaging of resonant multiples
We demonstrate for the first time that seismic resonant multiples, usually considered as noise, can be used for super-resolution imaging in the far-field region of sources and receivers. Tests with both synthetic data and field data show that resonant multiples can image reflector boundaries with resolutions more than twice the classical resolution limit. Resolution increases with the order of ...
متن کاملHyperlenses and metalenses for far-field super-resolution imaging.
The resolution of conventional optical lens systems is always hampered by the diffraction limit. Recent developments in artificial metamaterials provide new avenues to build hyperlenses and metalenses that are able to image beyond the diffraction limit. Hyperlenses project super-resolution information to the far field through a magnification mechanism, whereas metalenses not only super-resolve ...
متن کاملTwo-dimensional Fibonacci grating for far-field super-resolution imaging
A two-dimensional (2D) Fibonacci grating is used to transform evanescent waves into propagating waves for far-field super-resolution imaging. By detecting far-field intensity distributions of light field through objects in front of the 2D Fibonacci grating in free space at once, we can retrieve the image of objects with beyond λ/7 spatial resolution. We also find that the coherent illumination ...
