The granulometric analysis is a basic tool in the characterization process of particulate materials and can be determined through numerous methods, most notably the densimeter and laser diffraction ...

Discover why your favorite cat videos don't leak out of optical fibers. A transparent material, such as glass or water, can actually reflect light better than any mirror. All you have to do is look at ...

Abstract: We present an analytical formulation that shows the negative refraction of propagating waves and the growth of evanescent waves within a negative refractive index (NRI) lens made of a ...

Abstract: Partial discharge (PD) is a widely adopted method for the internal insulation detection of electrical transformers. The impact of the refraction and diffraction of the ultrasonic signal in ...
