Title:
GRADIENT INDEX LENS USING EFFECTIVE REFRACTIVE INDEX OF MICROSTRUCTURE ARRANGED IN RADIAL PATTERN, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/108994
Kind Code:
A1
Abstract:
The present invention relates to a gradient index lens using the effective refractive index of a microstructure operating in the terahertz frequency regions and mid-infrared regions at wavelengths of 0.8 µm to 3 mm, and to a method for manufacturing same. According to the present invention, based on the effective medium theorem, the effective refractive index is controlled by using a structure smaller than the middle infrared and terahertz wavelength, and a gradient can be provided for the refractive index in a radial direction and in an axial direction. Thus, beams in the middle infrared and terahertz frequency region can be converged.
