Infrared‐frequency coplanar striplines: Design, fabrication, and measurements

We investigate the feasibility of coplanar striplines (CPSs) in conjunction with infrared (IR) detectors. Because of unique attenuation and dispersion issues, the analytical formulas for transmis- sion-line parameters valid below a few hundred GHz are not applicable at IR. Therefore, we perform numerical modeling to determine these parameters (at 28.3 THz). A comparison of the modeling and the mea- sured response is presented. © 2005 Wiley Periodicals, Inc.
