The flows in a naturally evaporating liquid droplet confined by two flat plates were investigated experimentally. A diluted sodium-chloride (NaCl) aqueous solution was used to form the confined droplets. The evaporation of water at the free surface of the droplet built up a concentration gradient inside the solution, which induced a natural...

We study the dielectric constant dependent diffraction phenomena of single slit apertures, both theoretically and experimentally. We experimentally simulate perfect metal and real metal cases by investigating subwavelength diffraction by a single slit, both in nano-optical and in terahertz regimes, keeping the slit-width/wavelength ratio...
