A planar integrated left-handed microstrip line formed by linearly placed spiral elements is presented in this paper. This structure is simple to fabricate and is scalable to higher frequencies, which is ideal for microwave and millimeter-wave hybrid integrated circuit (HMIC) and monolithic integrated circuit (MMIC) applications. Left-handed propagations over this kind of transmission line are validated...
Presents an introduction to a special issue on metamaterials. The papers are very briefly described. In the mainstream metamaterial part of this issue, particular emphasis is placed on the so called left-handed, negative-reftactive-index (or negative index), or double negative (DNG) media. The second part of this issue concentrates on recent explorations and advances of EBG structures and related...
