Spaceplates are novel flat-optic devices that implement the optical response of a free-space volume over smaller length, effectively “compressing space” for light propagation. Together with flat lenses such as metalenses or diffractive lenses, spaceplates have potential to enable miniaturization any system. While fundamental and practical bounds on performance metrics been well studied in recent years, similar understanding ultimate limits is lacking, especially regarding issue bandwidth,...

Non-Hermitian systems have recently attracted significant attention in photonics. One of the hallmarks these is possibility realizing asymmetric mode-switching and omni-polarizer action through dynamic encirclement exceptional points (EPs). Here, we offer a new perspective on operating principle devices, theoretically experimentally show that linear can be easily realized—with same performance limitations—using simple configurations emulate physics involved encircling EPs without complexity...

Metals, semiconductors, metamaterials, and various two-dimensional materials with plasmonic dispersion exhibit numerous exotic physical effects in the presence of an external bias, for example static magnetic field or electric current. These phenomena range from Faraday rotation light propagating bulk to strong confinement directionality guided modes on surface are a consequence breaking Lorentz reciprocity these systems. The recent introduction relevant concepts topological physics,...

This study assessed the potential for savings and expanded with increased use of two biosimilar disease modifying anti-rheumatic drugs (DMARDs): (a) approved adalimumab biosimilars (b) first tocilizumab biosimilar, representing an established field a recent entrant in France, Germany, Italy, Spain, United Kingdom (UK).

Abstract Localized spoof surface plasmon polaritons (spoof-SPPs) in a graded spoof-plasmonic resonator chain with linearly increasing spacing are experimentally investigated at microwave frequencies. Transmission measurements and direct near-field mappings on this show that the propagation of localized spoof-SPPs can be cutoff different positions along under frequencies due to coupling between adjacent resonators. This mechanism used guide specific depending frequency thereby implement...

Optical systems with wide field-of-views (FOV) are crucial for many applications such as high performance imaging, optical projection, augmented/virtual reality, and miniaturized medical imaging tools. Typically, aberration-free a FOV is achieved by stacking multiple refractive lenses (as in “fisheye” lens), adding to the size weight of system. Single metalenses designed have potential replace these bulky and, moreover, they may be dispersion engineered spectrally broadband operation. In...

The recent discovery of the Lorentz symmetry-violating 'Type II' Weyl semimetal phase has renewed interest in study physics condensed matter systems. However, tuning exceptional properties this novel state remained a challenge. Optical lattices, created using standing laser beams, provide convenient platform to tune tunnelling parameters continuously time. In paper, we propose generalised two level system exhibiting type II points that can be realised ultra-cold atoms an optical lattice. is...

In electromagnetics and photonics, "nonlocality" refers to the phenomenon by which response/output of a material or system at certain point in space depends on input field across an extended region space. While nonlocal effects associated wavevector/momentum-dependence have often been neglected seen as nuisance context metasurfaces, emerging flat optics seeks exploit strong effective nonlocality enrich enhance their response. this Review, we summarize latest advances field, focusing its...

Breaking time-reversal or inversion symmetry are two ways of realizing a Weyl semimetal. We report that, in plasma medium with point dispersion, the broken realization is fundamentally more resilient against losses.
