Hollow-core metallic waveguides can simultaneously serve as efficient transmission media
in the terahertz (THz) region and gas absorption cells at the mid-infrared (MIR) band. Here …

An ultra-wide single-mode (SM) frequency bandwidth and low-flattened dispersion hollow-
core negative-curvature (HC-NC) terahertz (THz) waveguide is proposed. SM guidance is …

Optical fiber bundles have been widely used in microendoscopic biomedical imaging,
Raman microscopy, and depth-resolved imaging due to their flexibility, long-distance …

Terahertz (THz) devices, especially waveguide-type functional devices related to
transmission and control, are severely scarce due to the lack of effective design and …

Terahertz imaging has shown great potential in various fields and applications, such as non-
destructive testing, security screening and biomedical researches. However, many factors …

Although various terahertz (THz) functional devices based on artificial materials have been
widely proposed, their performance is still unsatisfactory due to the limitation of the involved …

At terahertz frequencies, where Ohmic losses are high, all-dielectric waveguides have
emerged as the basis of low-loss integrated circuits. Usually, advanced foundry fabrication …

In recent years, terahertz technology has developed rapidly, and one of the important topics
is low-loss, flexible, and low-cost terahertz waveguides. In this paper, PTFE tubes are used …

We propose a novel flexible and stretchable terahertz waveguide by 3D printing to guide
radiation from terahertz (THz) quantum cascade lasers (QCLs) lasing at the frequency of …
