Extraordinary optical transmission of light or electromagnetic waves through metal plates
periodically perforated with subwavelength holes has been exhaustively analyzed in the last …

We have designed, fabricated, and experimentally verified a highly sensitive plasmonic
sensing device in the terahertz frequency range. For a proof of concept of the sensing …

Metamaterial structures are artificial materials that show unconventional electromagnetic
properties such as photonic band-gap, extraordinary optical transmission and left-handed …

This paper presents a fully analytical model to determine the transmission and reflection
properties of planar 1-D distributions of metal strips or slits made in thin metal screens. In …

An epsilon-near-zero graded-index converging lens with planar faces is proposed and
analyzed. Each perfectly-electric conducting (PEC) waveguide comprising the lens operates …

In this paper we report directivity enhancement by a short-focal-length plano-concave lens
engineered by stacked subwavelength hole arrays (fishnet-like stack) with an effective …

This paper presents a quasi-analytical approach to study the classic topic of
transmission/reflection of electromagnetic waves through 1-D periodic arrays of strips/slits in …

In this paper, we theoretically analyze and design a dual-narrowband terahertz (THz)
absorber based on a hole array drilled into a metallic slab. A very high-quality factor (Q) is …

Metallic plates embedded between dielectric slabs and perforated by rectangular arrays of
subwavelength holes with a dense periodicity in one of the directions support extraordinary …

Polarization rotation or selection appears in materials with optical activity, or those with
Faraday effect, or in liquid crystals. In this letter we present a structure, with an analogous …
