2. 1. On-chip terahertz characterisation of liquids

   Author : Juan Cabello Sánchez; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; dielectric permittivity; Through-Reflect-Line TRL calibration; vector network analyzers VNA ; terahertz spectroscopy; isopropyl alcohol IPA ; coplanar waveguides CPW ; water; on-wafer measurements; planar Goubau line; Chip; liquids; microfluidic channels; scattering parameters; material properties;

   Abstract : Spectroscopy at terahertz frequencies can be used in a wide range of applications including radio-astronomy, pharmaceutical manufacturing control, and the study of processes in molecular biology. Biomolecular samples should preferably be studied in their native environment, water, however, water poses extreme attenuation for THz-frequency waves, deteriorating or even impeding analysis using these waves.

4. 2. Planar-Goubau-line components for terahertz applications

   Author : Juan Cabello Sánchez; Chalmers University of Technology; []
   Keywords : on-wafer measurements; power divider; microfluidic channels; silicon membrane; Impedance-matched load; stopband filter; vector network analyzers VNA ; terahertz spectroscopy; planar Goubau line; Through-Reflect-Line TRL calibration;

   Abstract : Terahertz-wave technology has a broad range of applications, including radio astronomy, telecommunications, security, medical applications, pharmaceutical quality control, and biological sensing. However, the sources, detectors, and components are less efficient at this frequency band due to parasitic effects and increased total losses, which hinder the performance of terahertz systems.
