چکیده

The field of metamaterials and the formalism of transformation optics have provided a prescription for constructing artificial dielectrics with unique properties such as light trapping and cloaking. Here, we describe a different approach to creating an inhomogeneous artificial medium, based on waveguide techniques, which does not rely on engineered subwavelengthscale components. We demonstrate a mirage effect in which an object several times larger than the selected wavelength is rendered invisible by bending a beam around it. VC 2012 American Institute of Physics.

Multifaceted terahertz applications of parallel-plate waveguide: TE1 mode

Presented is a review of recent work by the authors in which the lowestorder transverse-electric (TE1) mode of a parallel-plate waveguide (PPWG) is used for terahertz (THz) applications. This work adds a new dimension to the multitude of diverse THz applications made possible by PPWGs. Using the TE1 mode, demonstration is presented of an ultra-low loss THz waveguide, a highly sensitive microflu...

Parallel-Plate Waveguide Terahertz Time Domain Spectroscopy for Ultrathin Conductive Films

Development of techniques for characterization of extremely thin films is an important challenge in terahertz (THz) science and applications. Spectroscopic measurements of materials on the nanometer scale or of atomic layer thickness (2D materials) require a sufficient terahertz wave–matter interaction length, which is challenging to achieve in conventional transmission geometry. Waveguide-base...

Nature of subpicosecond terahertz pulse propagation in practical dielectric-filled parallel-plate waveguides.

It is analytically shown that the presence of submicrometer-sized air gaps between the dielectric and metal contact surfaces in a dielectric-filled metallic parallel-plate waveguide can have a dramatic effect on the guided-wave propagation of subpicosecond terahertz pulses. Through the use of metal-evaporated dielectric surfaces to overcome the imperfect contact problem, and a special air-diele...

A 2-D Artificial Dielectric With for the Terahertz Region

We demonstrate a 2-D artificial dielectric medium suitable for the terahertz region by exploiting the characteristic frequency dependence in the phase velocity of the lowest order transverse-electric mode of the parallel-plate waveguide (PPWG). This artificial medium exhibits a plasma-like behavior having a frequency-dependent refractive index that varies between zero and unity. Using this medi...

High-resolution waveguide terahertz spectroscopy of partially oriented organic polycrystalline films.

We have characterized the terahertz (THz) vibrational spectroscopy of organic polycrystalline thin films using the new experimental technique of waveguide terahertz time domain spectroscopy (waveguide THz-TDS). The organic materials used in this study are tetracyanoquinodimethane (TCNQ) and 1,3-dicyanobenzene (13DCB). For each material, a thin film is cast onto one of the inner surfaces of a me...
