Abstract :
The use of terahertz waves is a promising approach for the characterization of the informative molecular assembly and its evolution inside biological cell membranes. In this way we propose a new microprobe which combines microfluidic and microwave structures for measurements in the 140-220 GHz band. This structure, based on a thinned microstrip line, includes an excellent coplanar to microstrip transition in the full band, necessary for the on-wafer vectorial network analyser (VNA) measurements and the future temporal measurement up to 1.5 THz.
