Abstract:We investigate using finite element methods how sub‐micrometer to micrometer‐scale coplanar waveguide (CPW) can be used for the detection of fingerprint spectra of very small (of order 10−14 mL) volumes of analytes in the terahertz (THz) frequency range. The electric field distribution is investigated near the waveguide for various gap widths between the center conductor and ground plane using a finite element simulation (ANSYS High Frequency Structure Simulator, HFSS). Taking lactose monohydrate as an exempla… Show more
“…Park et al used a coplanar waveguide pair to achieve the absorption spectrum enhancement by about 14 times in the frequency band of 0.5–0.55 THz. 39 Fig. 1(a) gives the illustration of a coplanar waveguide, which enables the coupling of terahertz waves to the lactose block coated on the coplanar waveguide.…”
