Super-resolution imaging methods such as structured illumination microscopy and others
have offered various compromises between resolution, imaging speed, and biocompatibility …

The future success of semiconductor technology relies on the continuing reduction of the
feature size, allowing more components per chip and higher speed. Optical metamaterial …

The emergence of optical metamaterials opens new opportunities for spatial pattern
compression from the micro-to nanoscale. By exploiting strongly anisotropic optical …

Confining light into a sub-wavelength area has been challenging due to the natural
phenomenon of diffraction. In this paper, we report deep sub-wavelength focusing via …

Plasmonic hyperbolic metasurfaces have emerged as an effective platform for manipulating
the propagation of light. Here, confined modes on arrays of silver nanoridges that exhibit …

We report the design of a high-throughput gradient hyperbolic lenslet built with real-life
materials and capable of focusing a beam into a deep sub-wavelength spot of λ/23. This …

Hyperlens consisted by period plasmonic metamaterials is an interesting technology for the
optical imaging of arbitrary objects beyond the diffraction limit in the far field, which has great …

In this paper we show that engineering both phase and amplitude of the scattered light can
be employed in designing metalenses with either higher resolution or apodized focal spots …

Due to the excellent ability to break the diffraction limit in the subwavelength range,
metamaterial-based hyperlens has received extensive attention. Unfortunately, radial …

Subwavelength periodic gratings, which are widely used in optical systems, exhibit only zero-
order diffraction, owing to a diffraction limit. This limits the resolution of optical critical …
