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. [--]
