Electromagnetic radiation is pervasive. It comes in many forms, including radio waves, microwaves and high-energy X-rays and gamma rays. But what, precisely, is it? Electromagnetic radiation is the ...

The polarizability of atoms and molecules gives rise to optical forces that trap particles and a refractive index that guides light beams, potentially leading to a self-guided laser and particle beam ...

The optical radiation force can deform dielectric material surfaces, such as photo-isometric azopolymers, due to their electric susceptibility, and the shape can be controlled by the artificial ...

There are many opportunities for graduate student research in computational physics of plasmas and beams, including the study of nanoscale vacuum channel transistors, the study of the formation of ...
