However, can an equal number of isomer resonance units also form a "composite" metamaterial or metasurface like molecules ? The novel optical phenomena and light field manipulation functions that ...

Immerse yourself in the dynamic world of optical communications and signal processing with our specialised programme. You will explore advanced topics in photonics, optical communications devices, ...

Optical materials are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each ...

Polarimeters are scientific instruments used for measuring the rotation of the plane of polarized light as it passes through a sample of a compound which exhibits optical activity. Many chemical ...

Optical illusion psychology tests reveal hidden personality traits based on first perceptions. In a specific cat-stairs illusion, seeing the cat walk down indicates cautiousness and attention to ...

A NASA astronaut who just returned from the International Space Station has been hospitalized for an unspecified medical ...

A team, led by Dr. Julia Schroeder and Dr. Jamie Dunning from the Department of Life Sciences, found that male sparrows that ...

An optical lens is a transparent optical component used to converge or diverge light emitted from a peripheral object. The transmitted light rays then form a real or virtual image of the object.
