| Research Abstract |
A film-type metamaterial with rejection characteristics is investigated. It is composed of parallel metal strips put two-dimensionally on a dielectric substrate. First, the structure is discussed for obtaining the high performance of the rejection characteristics in microwave region. The structure with characteristic independent of polarization direction of the incident wave is realized by using a new metal strip shape. The dependence on the incident angle of the wave is also improved. By adjusting the shape of three parallel strips, the rejection frequency band can be broadened. The metamaterial with rejection characteristics in an infrared range is fabricated using a lithography technique and the transmission characteristics reflecting the strip pattern is obtained.
