We present the design and implementation of a periodically loaded transmission line, which simultaneously exhibits negative refractive index (NRI) and negative group delay (and, hence, negative group ...

Laser direct writing functional optical materials enable high-resolution and optically thin computer-generated holograms with a wide range of applications. However, the traditional material system ...

Information on the density (ρ) and refractive index m (=n − ik) of elemental carbon (ECa) and organic matter (OMa), the main carbon components of atmospheric aerosols, has frequently been obtained ...

High-precision, rapid, non-contact measurement of solution concentrations is crucial for accurate formulation. In this letter, we introduce an ethanol concentration interferometer based on ...
