Small-size metamaterial perfect absorber operating at low frequency

Son Tung Bui、Van Khuyen Bui、Van Dung Nguyen 等 7 位作者2014-11-04Advances in Natural Sciences Nanoscience and Nanotechnology

A small-size metamaterial perfect absorber operating at low frequency is proposed. Due to the special design, the unit-cell dimension with respect to wavelength is very small, a/ λ ∼ 1/17, at the absorption frequency of 377 MHz. The absorption frequency is strongly dependent on the length of zigzag wire. In addition,…
