In addition to our other problems, we must also contend with transmission (with attenuation), reflection, refraction, diffraction, absorption, and scattering. In addition to our other problems, we ...

In conventional optical components, such as lenses or gratings, the propagation of light is usually manipulated by reflection, refraction or diffraction. For example, a wavefront can be modified using ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

Most people know that light travels in a straight line unless something acts upon it to change its direction. The three most common methods of changing the direction of light are refraction, ...

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...
