20100134897	PROJECTING TYPE HYPER-LENS AND METHOD OF MANUFACTURING THE SAME - Disclosed are a projecting type hyper-lens and a method of manufacturing the same. The projecting type hyper-lens includes a main lens layer and a substrate layer. A front surface of the main lens layer is recessed. The substrate layer supports the main lens layer. A front central portion of the main lens layer protrudes beyond a surface of the substrate layer. The projecting type hyper-lens allows an object to move towards a front surface of the hyper-lens until a distance between the front surface of the hyper-lens and the object is smaller than a half-wavelength of light, and thus images an object smaller than a half-wavelength of used light. Evanescent waves scattered from an object is used in a manner convenient to a user.	06-03-2010
20110148550	METAMATERIAL TRANSMISSION LINE APPARATUS AND METHOD OF IMPLEMENTING THE SAME - A metamaterial transmission line for transmitting an electromagnetic wave. The metamaterial transmission line may include a substrate including a substrate configured to include a an upper portion and a lower portion on which a ground plane is formed, a signal line configured to be formed on the substrate, and a defected ground structure configured to include an etched region and two metal portions, wherein the etched region is generated by etching a part of the ground plane and the metal portions extend from the signal line and are disposed on the etched region.	06-23-2011

20110149718	FAST FOURIER TRANSFORM APPARATUS AND METHOD - A fast Fourier transform (FFT) apparatus and method. The FFT method may include finding a number of subcarriers carrying valid data in reception data, determining a Fourier transform order on the basis of the number of subcarriers, performing complex multiplication on the reception data, and then performing a Fourier transform of the determined Fourier transform order. Using the FFT method, it is possible to reduce the amount of computation and the complexity of an FFT in a frequency division multiplexing (FDM) system and simplify a hardware structure.	06-23-2011

20110102773	IDENTIFICATION APPARATUS OF OPTICAL CABLE AND IDENTIFICATION METHOD - An optical cable identification apparatus is disclosed. The optical cable identification apparatus capable of identity an optical cable by disturbing an optical fiber, existing inside an optical cable desired to be identified, from an outside. An optical unit transmits two optical signals to a single strand of optical fiber inside the optical cable, and detects a phase difference, a time difference, and light intensity between two optical signals which are reflected due to the disturbance from the outside. A single-fiber ending unit generates the time difference. A signal processing unit removes noise from the two reflected optical signals and demodulates the optical signals. A sound output unit outputs the optical signals from the signal processing unit as sounds.	05-05-2011
