Bonding in Metals

Bonding in Metals

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Metal-Ligand Bonds

Metal-Ligand Bonds

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Background:

Metasurfaces offer potential for ultra-compact and integrated meta-optics.
Combining nanoimprinting and holography is key for meta-devices but faces challenges in efficiency, design, and fabrication due to layering methods.
Existing multi-functional metasurfaces often require complex fabrication and design by combining numerous resonators.

Purpose of the Study:

To introduce a novel technique for a tri-operational metasurface by merging PB phase-based helicity-multiplexing and Malus's law of intensity modulation.
To resolve the extreme-mapping issue in a single-sized metasurface scheme without increasing nanostructure complexity.
To demonstrate simultaneous control of near and far-field operations using a single-sized metasurface.

Main Methods:

Developed a novel technique merging PB phase-based helicity-multiplexing and Malus's law of intensity modulation.
Fabricated a multi-functional metasurface using single-sized zinc sulfide (ZnS) nanobricks.
Demonstrated proof of concept for simultaneous near and far-field operations.

Main Results:

Successfully implemented a multi-functional design strategy with conventional single-resonator geometry.
Reproduced two high-fidelity images in the far field.
Projected one nanoimprinting image in the near field using the single-sized ZnS nanobricks.

Conclusions:

The proposed information multiplexing technique is a potential candidate for optical storage, information-switching, and anti-counterfeiting.
This novel technique overcomes limitations of existing methods by enabling multi-functionality without increased design or fabrication complexity.
The developed tri-operational metasurface demonstrates the viability of simultaneous control of near and far-field optical functions.
