The fish-scale bio-inspired nanostructured coatings feature tunable light refraction and reflection, tunable surface wettability and damage-tolerant mechanical properties. The salient properties ...

The idea of creating negative refraction by exploiting the collective electron acceleration (inertia) effect, or kinetic inductance, was theoretically proposed for specific arrangements of three ...

This is known as refraction and causes a visual distortion for an archer fish looking at prey above the surface. In essence, any potential meal is not actually where it appears to be unless the ...

archer fish evidently can estimate three-dimensional speed of an aerial object with sufficient accuracy despite the complex, strongly viewpoint-dependent metric distortions due to refraction at ...

If water exhibited negative refraction, fish swimming in a pool would appear to be in the air above the water. "This is an important step toward creating a cloak," Zhang said last week.

If water exhibited negative refraction, fish swimming in a pool would appear to be in the air above the water. “This is an important step toward creating a cloak,” Zhang said Monday.

The new research proves that the fish-eye has unlimited resolution in principle, and, as it does not need negative refraction, it may also work in practice. "The theory was inspired by ideas for ...
