Microwave transmissivity of a metamaterial–dielectric stack
CAM Butler, J Parsons, JR Sambles, AP Hibbins… - Applied Physics …, 2009 - pubs.aip.org
A metamaterial layer comprising of a conducting square mesh surrounding subwavelength
holes has a largely pure imaginary effective refractive index. We explore the microwave
transmissivity of a stack of such metamaterial layers separated by dielectric spacers. As
expected, a family of high transmissivity bands is experimentally observed. It is found that
the lowest frequency edge is independent of the number of unit cells making up the structure
and is highly tunable by appropriate geometrical design of the metamaterial layers.
