TL;DR: This special issue presents a cross-section of recent progress in the rapidly developing area of optics of hyperbolic metamaterials.

TL;DR: High-resolution, scattering-type near-field optical microscopy has been used and numerical and analytical modeling of the mode structure is in agreement with the experimental observations and indicates the presence of the nonlocal response associated with cylindrical surface plasmons of nanowires.

TL;DR: Experimental evidence of excitation of additional wave in nanorod metamaterials in ENZ regime is presented and Analytical description of the phenomenon is developed and the effect on the optical response of the system is discussed.

TL;DR: The high sensitivity of plasmonic nanorod metamaterials to variations in the refractive index of their surroundings is taken advantage of to demonstrate the ultrasensitive detection of acoustic waves.

TL;DR: In this article, the authors present a technique capable of producing subwavelength focal spots in the far-field of the source in planar non-resonant structures, which combines the diffraction gratings that generate the high-wave vector-number modes and planar slabs of homogeneous anisotropic metamaterials that propagate these waves and combine them at the sub-wave focal spots.
