Page 28: Research news on Optical & microwave phenomena

Optical & microwave phenomena as a research area investigates the generation, propagation, interaction, and detection of electromagnetic radiation spanning the optical (visible, ultraviolet, infrared) and microwave spectral ranges, with emphasis on their underlying physical mechanisms and cross-regime analogies. It encompasses coherent and incoherent light–matter interactions, waveguiding, scattering, nonlinear effects, resonances, and quantum electrodynamical aspects, as well as microwave cavity dynamics, dispersion, and near-field behavior. The field supports development of advanced spectroscopies, imaging modalities, communication and sensing technologies, and enables engineered materials and structures (e.g., photonic and microwave metamaterials) that tailor electromagnetic response across these frequency bands.

Targeted photothermal treatment for blood clots shows promise

Nanoparticles loaded with dye that release heat upon near-infrared irradiation could provide the key to more targeted treatment for blood clots, according to new research by the Baker Institute and Swinburne University.

Physicists see light waves moving through a metal

When we encounter metals in our day-to-day lives, we perceive them as shiny. That's because common metallic materials are reflective at visible light wavelengths and will bounce back any light that strikes them. While metals ...

Researchers use light to control magnetic fields at nanoscale

In thin, two-dimensional semiconductors, electrons move, spin and synchronize in unusual ways. For researchers, understanding the way these electrons carry out their intricate dances—and learning to manipulate their choreography—not ...

Physicists invent intelligent quantum sensor of light waves

University of Texas at Dallas physicists and their collaborators at Yale University have demonstrated an atomically thin, intelligent quantum sensor that can simultaneously detect all the fundamental properties of an incoming ...

Intrinsic optical nonlinearities and carrier dynamics of InSe

Recently, researchers in Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences carried out a systematic investigation on the microscopic optical nonlinearities and transient carrier dynamics ...

Graphene-hBN breakthrough to spur new LEDs, quantum computing

In a discovery that could speed research into next-generation electronics and LED devices, a University of Michigan research team has developed the first reliable, scalable method for growing single layers of hexagonal boron ...
