  • Fluid Transfer Apparatus
    Publication number: 20110171043
    Abstract: The invention relates to an apparatus for transporting a fluid, an object to be transported, in the vertical or horizontal direction. More particularly, the apparatus of the present invention has a surface formed into a pattern recursively alternating in a fluid transfer direction such that the surface of the apparatus has a contact angle different from that of the fluid, and the transportation of the fluid is controlled by the hydrodynamic force generated by the difference of the contact angles.

  • Terahertz or infrared filter using shape resonance
    Patent number: 7746550
    Abstract: A filter having a high transmittance. The filter includes a substrate having a first surface and a second surface, and a periodic or random array of through-holes formed so as to pass through the first surface and the second surface. The through-hole has a size of subwavelength at a range of infrared and terahertz wave. Here, transmission resonance characteristic of incident light on the first surface is controlled by a shape of the through-hole.
