Beruete, M. Navarro-Cía, M. Sorolla, and I. Campillo Phys. Rev. B 79, 195107 and may be found at https://doi.org/10.1103/PhysRevB.79.195107.In this letter we present simulation and experimental results of a left-handed converging biconcave metallic lens made of stacked subwavelength hole arrays SSHAs working in the millimeter wave range with additional features of polarizer and frequency filter. The converging behavior of the biconcave metallic lens, in contrast with focusing biconvex dielectric lenses, comes as a result of the negative index of refraction that characterizes double-negative metamaterials made of SSHAs. The presented results may find application in the design of lenses and devices both in the microwave, infrared and optical ranges.3 p.application/pdfeng© 2009 American Institute of PhysicsThis article may be downloaded for personal use only.
