“…The metasurfaces also play a crucial role in manipulating the polarization of light [11][12][13][14]. It is well known that, besides the enhanced optical transmission effect, a metal film milled with one-dimensional slits or two-dimensional rectangular holes behaves as a nanoscale plasmonic polarizer [15,16].…”

The conventional linear polarizer only allows the electric component parallel to the polarizer axis to pass through whereas prohibits the vertical component. We propose that a specially-designed single-layer plasmonic polarizer can couple both parallel and vertical electric components to the transmission, thus breaking the classical law of Malus. A variety of anomalous polarization effects, such as the asymmetric polarization-angle dependence, enhanced polarization filtering with wide polarization angle, and tunable polarization rotation from 0 o to 90 o , can be resulted. To understand the effects, the generalized law of Malus, originating from the superposition principle, has been presented and analyzed. This provides a basis for studying the interference-type plasmonic polarizers, where the interference effect and polarization effect are combined together. The difference between the plasmonic and conventional polarizers is of both fundamental and practical interests.

“…They have many extraordinary optical properties, such as surface enhanced spectroscopy [5,6], enhanced transmission [7−9], sensitive bio-sensing [10,11], negative refractive index [12−14], double negative materials [15], and high resolution imaging [16,17]. The metallic gratings consisting of narrow slits [18] may become transparent for extremely broad bandwidths under the oblique incidence. In addition, ultrathin, broadband, highly efficient [19,20], and freely tunable [21] metamaterial-based polarization converters have been realized.…”

Optical metamaterials can concentrate light into extremely tiny volumes to enhance their interaction with quantum objects. In this paper, a cylindrical microcavity based on the Au-dielectric-Au sandwiched structure is proposed. Numerical study shows that the cylindrical microcavity has the strong ability of localizing light and confining 10 3 --10 4 -fold enhancement of the electromagnetic energy density, which contains the most energy of the incoming light. The enhancement factor of energy density G inside the cavity shows the regularities as the change in the thickness of the dielectric slab, dielectric constant, and the radius of gold disk. At the normal incidence of electromagnetic radiation, the obtained reflection spectra operate in the range from 4.8 μm to 6 μm and with the absorption efficiency C (C=1-R min ), which can reach 99% by optimizing the structure's geometry parameters, and the dielectric constant. Due to the symmetry of the cylindrical microcavities, this structure is insensitive to the polarization of the incident wave. The proposed optical metamaterials will have potential applications in the surface enhanced spectroscopy, new plasmonic detectors, bio-sensing, solar cells, etc.

Extended Malus law with terahertz metallic metamaterials for sensitive detection with giant tunable quality factor

We study a polarizer-analyzer mounting for the terahertz regime with perfectly conducting metallic polarizers made of a periodic subwavelength pattern. We analytically investigate the influence on the transmission response of the multiple reflections which occur between polarizer and analyzer with a renewed Jones formalism. We demonstrate that this interaction leads to a modified transmission response: the extended Malus' Law. In addition, we show that the transmission response can be controlled by the distance between polarizer and analyzer. For particular set-ups, the mounting exhibits extremely sensitive transmission responses. This interesting feature can be employed for high precision sensing and characterization applications. We specifically propose a general design for measuring electro-optical response of materials in the terahertz domain allowing detection of refractive index variations as small as 10 −5 .
