Engineers are increasingly embracing computer simulations to test the structural integrity of their prototypes. These computer simulations are based on the finite element method (FEM) and finite element analysis (FEA), which work in unison to give engineers insight into the structural behavior of particular designs, so they can locate weak points and improve them. While […]
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 […]
In 2020, photonics researchers used the finite element method (FEM) to make a number of exciting discoveries in the field of optics. As discussed in a previous post, FEM is a numerical solution that breaks down a much larger, complex problem into a series of smaller ones (“finite elements”) in order to make the overall […]
The majority of medical, scientific, and industrial applications utilize high-power diode-lasers (HPDLs). Due to the common use of HPDLs, it’s more important than ever to prevent optical and physical malfunctions in high-power laser packages. However, as laser technology has become more advanced, HPDL output power has gotten larger, and with it, the waste-heat energy density […]
Exciting developments are happening in the fields optics and photonics. Some of these innovations are being made with the help of the finite element method (FEM). As discussed in a previous post, FEM is a numerical solution for a complex problem, which is used to create simulations. These simulations help researchers understand how all the […]
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 […]
Photonics is the science of producing, manipulating, and discovering light waves and photons (light particles). The field covers a number of technologies like lasers and fiber-optics. The finite element method (FEM) can be used to create a range of photonics applications that can be used in astronomy, telecommunications, sensing, chemistry, biomedical R&D, and more. How […]
The finite element method (FEM) and finite element analysis (FEA) work together to give engineers insight into the structural behavior of particular designs, so they can locate weak points and improve them. FEM: Developed by engineers in the mid-1950s, FEM provides a numerical solution for a complex problem, which allows for some level of error. […]
