abstract

  • Complex permittivity measurements of liquids and living cell suspensions with Finite Ground Coplanar waveguides (FG-CPW) in a SU-8 reservoir are presented. A simple deembedding method based on ABCD matrices is described. Complex permittivity measurements of reference liquids such as methanol and isopropanol show good agreement with theoretical values. Results on living cell suspensions (human embryonic kidney cells) measured over the frequency range of 1 to 32 GHz are described. Dimethylsulfoxide (DMSO) toxicity tests on cell suspension show time dependent permittivity changes due to cell disintegration and diffusion process. © 2008 IEEE.
