Lying between optical and microwave ranges, the terahertz band in the electromagnetic
spectrum is attracting increased attention. Optical fibers are essential for develo** the full …

Several classes of non-planar metallic and dielectric waveguides have been proposed in
the literature for guidance of terahertz (THz) or T-ray radiation. In this review, we focus on the …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

The expanding role of refractive index measurement in many fields including chemistry,
biology and medicine, food industry, process control, and environmental monitoring, has led …

A low-loss hollow core terahertz waveguide based on Kagome photonic crystal structure has
been designed and fabricated by 3D printing. The 3D printed waveguide has been …

We present a numerical and experimental investigation of a low-loss porous-core
honeycomb fiber for terahertz wave guiding. The introduction of a porous core with hole size …

In this paper, a novel polarization-maintaining single-mode photonic crystal fiber (PCF) has
been suggested for terahertz (THz) transmission applications. The reported PCF has five …

Modal characteristics of the THz pipe waveguide, which is a thin pipe consisting of a large
air core and a thin dielectric layer with uniform but low index, are investigated. Modal indices …

Research on reducing material absorption in Terahertz (THz) waveguides has lead to
development of guiding structures with transmission losses as low as 1 dB/m. Among …

Research on terahertz waveguides is experiencing a tremendous growth due to their
importance for compact and robust THz systems. However, designing compact, broadband …
