We propose a straightforward and effective approach to design, by pattern-tunable strain-engineering, photonic topological insulators supporting high quality factors edge states. Chiral strain-engineering creates opposit...

Nano-patterned colloidal plasmonic metasurfaces are capable of manipulation of light at the subwavelength scale. However, achieving controllable lithography-free nano-patterning for colloidal metasurfaces still remains a...

Quantitative analysis of line edge roughness (LER) is very important for understanding the root causes of LER and thereby improving the pattern quality in near-field lithography (NFL), because LER has become the main lim...

Complex-amplitude holographic metasurfaces (CAHMs) with the flexibility in modulating phase and amplitude profiles have been used to manipulate the propagation of wavefront with an unprecedented level, leading to higher ...

In the last decades, the study of Afro-Spanish varieties that developed during the Colonial period in the Americas has seduced many scholars. The analysis of these Afro-Hispanic speech patterns is crucial to determine th...

This book is the result of an investigation of the osteology of the turtle (Trachemys callirostris callirostris) and the morrocoya or morrocoy (Chelonoidis carbonaria), motivated by the need to identify at the level of s...

Health and biomedical research are undergoing rapid advancement. New therapies, digital tools, and data-driven methods emerge on a daily basis, often accompanied by audacious claims and rapid shifts in attention. For rea...

Herein we present a detailed analysis of the optical response of artificial opal films realized employing a near-field scanning optical microscope in collection and transmission modes. Near-field patterns measured at the...

Achieving a pre-designed scattering pattern from an ultra-compact platform is highly desired for on-chip integration optics, but conventional techniques suffer from the limitations of bulky size, wavelength-scale modulat...

A brief, tutorial account is given of the differences between the near and far regions of the electromagnetic field emphasizing the source-dependent behavior of the former and the universal properties of the latter. Fiel...

In this paper, the resonance modes exhibited by a hybrid nanostructure have been disentangled in the far-field owing to narrow-band fluorescence nano-reporters. Hybrid plasmonic-photonic crystals were fabricated using la...

Limited telecommunication network services, even for 2G technology, in some regions due to living in small islands, range of hills and blank spot areas are experienced in Indonesian Republic. One of solutions is proposed...

With rapid development of holography, metasurface-based holographic communication scheme shows great potential in development of adaptive electromagnetic function. However, conventional passive metasurfaces are severely ...

Optical standing waves are intrinsically nanometric, spatially fixed interference-field patterns. At a commensurate scale, metallic nanotips serve as coherent, atomic-sized electron sources. Here, we explore the localize...
