Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

Based on a suitable band structure, the synergistic effect of oxygen vacancy defects and an electromagnetic field facilitates electron transfer. This process thereby achieves broadband absorption ...

Light is a wave. Like a wave on the ocean, it represents an oscillation — though not a wave of the water’s surface, but of the electromagnetic field that permeates space. In physics, we say a wave is ...

Handedness-selective chiral transport is an intriguing phenomenon that not only holds significant importance for fundamental research, but it also carries application prospects in fields such as ...

For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...

Ripples arise while characterizing devices at RF and microwave frequencies. RF engineers need to make sure that measurement set-up is properly calibrated and matched in order to avoid measurement ...

Gravitational waves from inflation generate a faint but distinctive twisting pattern in the polarization of the cosmic microwave background, known as a "curl" or B-mode pattern. For the density ...
