A coplanar waveguide system for cells exposure during electrophysiological recordings

In order to investigate the biological effects of microwave electromagnetic fields as those emitted from mobile telecommunications equipment, a suitable exposure system has been designed. The system is specific for real time acquisition of cellular membrane ionic currents, i.e. patch-clamp recordings. Both the numerical and the experimental characterization of the system is considered, in terms of EM field distribution and SAR inside the Petri dish containing the biological target. Results show a good efficiency of the system in terms of SAR induced in the sample by incident input power.
