A micro-nano hierarchical structure for drag reduction and microbial adhesion prevention includes a metallic support plate having formed on its surface a plurality of arrays which are each composed of a plurality of metallic micro-structures and which are arranged in parallel, and a plurality of metallic nano-structures uniformly formed on the micro-structures and the support plate.

Micro-nano hierarchical structure for drag reduction and microbial adhesion prevention and marine structure comprising the same

The present invention relates to an optical head for revealing near field through beams irradiated from a light source of a far field optical system, the optical head including: a flexible substrate made of a soft material and adapted to allow the optical head to be brought into close contact with a measured object and attached thereto even if the measured object has a curved or flat surface; and a near-field revelation part located between the measured object and the flexible substrate in such a manner as to have one side brought into contact with the flexible substrate and the other side detachably attached to the measured object and adapted to reveal the near field through the beams irradiated from the light source.

Dynamic optical head and imaging device using flexible nano film optical structure

The present invention relates to a dynamic optical head layer in an optical lithography system forming patterns on a substrate, the dynamic optical head layer being detachably mounted on the substrate, and the dynamic optical head layer includes a first dielectric layer formed on a top portion thereof, a second dielectric layer formed on a bottom portion thereof, and an dynamic nano aperture layer formed between the first dielectric layer and the second dielectric layer, wherein the dynamic nano aperture layer is made of a material having optical anisotropy, and the first dielectric layer and the second dielectric layer are made of oxide-based materials, nitride-based materials, and carbide-based materials.
