Abstract: Control of electromagnetic fields using graded photonic crystals (GPhCs) is explored using equations of Hamiltonian optics. Contrary to previous works devoted to the long-wavelength regime ...

Electromagnetic waves help to solve partial differential equations at the speed of light. Credit: R.G. MacDonald ... from heat diffusion to particle motion and wave propagation. Although some PDEs can ...

Understanding how light travels through various materials is essential for many fields, from medical imaging to manufacturing. However, due to their structure, materials often show directional ...

in order to avoid unwanted reflections of light or microwaves. For sound waves, ten years ago researchers succeeded in suppressing their propagation in the backward direction; however, this also ...

According to Ramírez, fully understanding the propagation channel and how waves travel ... network deployments in industrial environments. This sheds light on the operation of millimeter wave networks ...

In addition, the physical mechanism of wave propagation in complex environments should be investigated across different scales. For example, to understand the interaction between light transmission ...

Topological plasmonics provide insights for the manipulation of light. Analogous to the exotic nature of topological ... of electron impact positions to control the direction of propagation and ...

When the light waves pass through the slits ... performed a similar experiment where the obstacles to the light’s propagation were separated in time. “The temporal manipulation of waves ...

Silverman, formerly of New York University’s Institute of Mathematical Sciences* describes the phenomena associated with the propagation of electromagnetic and acoustic waves through atmospheric ...

Now, however, researchers have created a device that uses travelling sound waves to break this symmetry ... In optical vortices, the wavefront of a beam of light spirals around the beam’s central ...
