TLDR
In this paper, an original way to excite surface waves on a single-wire transmission line was proposed, which is very well suited for the terahertz frequency range and allows the investigation of biological entities with high spatial resolution.
Abstract
In this paper, we report results on an original way to excite surface waves on a single-wire transmission line. Although these waves were proposed many decades ago by Goubau, the novelty of our structures is to achieve a broadband planar excitement. This configuration is very well suited for the terahertz frequency range and allows the investigation of biological entities with high spatial resolution with the use of novel biomicroelectromechanical systems, which include microfluidic functions. From experimental results, we compare different types of transitions from coplanar waveguides, and different substrates are also used. We show that the excitation is highly efficient and broadband for structures on a quartz substrate

Broadband and high-efficiency conversion from guided waves to spoof surface plasmon polaritons

TL;DR: In this article, a smooth bridge between the conventional coplanar waveguide with 50 Ω impedance and plasmonic waveguide (e.g., an ultrathin corrugated metallic strip) has been proposed in the microwave frequency, which converts the guided waves to spoof SPPs with high efficiency in broadband.

Method and apparatus for coupling an antenna to a device

TL;DR: In this paper, the authors describe a system that receives, by a feed point of a dielectric antenna, electromagnetic waves from a core coupled to the feed point without an electrical return path, and radiates a wireless signal responsive to the electromagnetic waves being received at the aperture.

Backhaul link for distributed antenna system

TL;DR: In this paper, a distributed antenna and backhaul system provide network connectivity for a small cell deployment using high-bandwidth, millimeter-wave communications and existing power line infrastructure, rather than building new structures, and installing additional fiber and cable.
Patent

Remote distributed antenna system

TL;DR: In this article, a distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas.

Open Wire Lines

TL;DR: In this article, the properties of two-wire and single-wire transmission lines are compared on a comparative basis and the main domain of the twowire lines lies in the frequency range below 100 cm and that of the single wire line in the range above 100 cm.

The interaction between Terahertz radiation and biological tissue

TL;DR: In this paper, a review of the current understanding of the interactions between terahertz radiation and biological molecules, cells and tissues is presented, showing that at frequencies below approximately 6 THz the interaction may be understood as a classical EM wave interaction, whereas at higher frequencies transitions between different molecular vibrational and rotational energy levels are more readily understood using a quantum-mechanical framework.

A functionalized THz sensor for marker-free DNA analysis

TL;DR: A novel resonant THz sensor for the label-free analysis of DNA molecules that allows the direct detection of DNA-probe molecules at functionalized electrodes via hybridization and can be extended to a parallel analysis of multiple DNA sequences.
