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 ...
THE increasing application to various radio purposes of ultra-short electric waves of less than 10 m. in wave-length has given a new stimulus to the problem of calculating the field strength at ...
In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...
Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...
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, ...
