On cold, sunny days, tiny ice crystals in the atmosphere can create breathtaking displays like halos, sundogs, and light pillars. Cold winter days don’t just bring frigid temperatures, they can also ...

Abstract: This paper presents an efficient continuous-wave THz computed tomography, which can be achieved based on the utilization of deep learning approach together with object shape information. A ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

It would be appreciated if a reference to the following work, for which this package was originally built, is included whenever this code is used for a publication ...

Refraction is the change in the direction of light due to a change in its speed as it enters a different medium. While the speed of light is constant in a vacuum, it decreases in denser materials, ...

In this work a Finite-Difference Frequency-Domain (FDFD) propagation method for complex urban environments is proposed. The formulation starts from the discretization of the Helmholtz equation for the ...

JACKSONVILLE, Fla. — Ever spot a rainbow on top of a thundercloud? Some of our First Coast News Weather Watchers did on Wednesday afternoon in the Jacksonville area. The technical term for this is an ...

Diffraction refers to the bending of waves, such as light, when they encounter obstacles or pass through small openings. The size of the opening relative to the wavelength of light influences the ...

This work achieves the refraction and reflection of flexoelectric-induced directrons at interfaces. With identical physical properties of the media on both sides of the interface, as well as uniform ...
