Researchers from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, have demonstrated for the first time that the optical properties of metals can be altered using mechanical strain.
- The study focused on the plasmon resonance of metals.
- Plasmon resonance governs how a metal interacts with light.
- The researchers showed this resonance can be tuned by changing the metal's structure through mechanical deformation.
The finding opens a new, mechanical way of controlling how metals respond to light.
