A metamaterial for an electromagnetic wave filter includes a substrate; and a film disposed on the substrate and having a set of slots arranged to form a rotationally symmetric pattern, which is patterned in an intaglio shape, or a set of structures arranged to form a rotationally symmetric pattern, which is patterned in an embossed shape, to control a transmission rate according to polarization of an electromagnetic wave incident on the film. The set of slots or the set of structures have an array angle that is determined such that the transmission rate and a reflectivity thereof have constant values according to the polarization of the electromagnetic wave incident on the film, and have a chloroplast molecular structure pattern in which the set of slots or the set of structures are arranged in pentagonal and hexagonal shapes.

The present invention relates to a otitis media diagnosis system using terahertz electromagnetic waves, which can diagnose otitis media using terahertz electromagnetic waves in a non-invasive manner, and which can accurately diagnose otitis media by acquiring images on the tympanic cavity using terahertz electromagnetic waves with excellent transmittance, and which can quickly and accurately divide exudative otitis media and suppurative otitis media using terahertz electromagnetic waves that are sensitive to moisture, and which is safe to a body using terahertz electromagnetic waves. The otitis media diagnosis system includes a terahertz probe including a generating unit for radiating terahertz electromagnetic waves from the outside of an ear toward a tympanic cavity and a detection unit for detecting the reflected terahertz electromagnetic waves reflected from the tympanic cavity.

A semiconductor memory device having a data line structure is disclosed which is capable of eliminating a noise interference between data lines and enhancing an integrity of a memory device. In the semiconductor memory device, a pair of data lines are not aligned on the identical plane. Namely, it is separated into an upper layer line and a lower layer line using an insulation film, wherein the data lines forming a plurality of pairs of the data lines are aligned in the upper wiring line and lower wiring line on a semiconductor substrate, and have at least one intersected portion therebetween.
