Motivated by the idea of using coplanar waveguides (CPW) as a sample cell to trigger and control chemical reactions, the infrastructure for designing, testing, and simulating these transmission lines was developed. Unlike any other method CPWs offer the opportunity to create extreme high field strengths of up to 1V/nm in combination with an excitation length of pico- and sub-picoseconds. A fundamental understanding and characterization of CPWs in different frequency ranges was obtained and theoretical limits to field strength and frequency were derived. A test facility was designed, built, and commissioned to characterize the electric properties of transmission lines built in integrated circuit technology. The important part of the measurements and results will be presented.
