Tunable “Metalens” is a Breakthrough in Photonics

MIT engineers recently designed a tunable “metalens” that can zero in on objects at multiple depths. The lens, constructed from a transparent “phase-changing” material capable of rearranging its atomic structure after heating, is capable of transforming how its material interacts with light. The invention is a breakthrough in the field of photonics. Traditionally, changing the […]

The Finite Element Method Continues to Drive Innovation in Photonics

The optics and photonics fields are creating groundbreaking applications for astronomy, telecommunications, sensing, chemistry, biomedical research & development. Recently, researchers from Pennsylvania State University demonstrated how metasurfaces with unparalleled controllability of light may be able to transform traditional optics. To do so, they used a simulation that applied the finite element method (FEM). As discussed […]
