The exposure system, especially designed for electrophysiological patch-clamp recording, has been described in [Liberti et al., 2004]. An open propagating structure consisting of a Co-Planar Waveguide (22.0 cm x 10.2 cm x 0.4 cm) was positioned on the stage of a microscope. The upper side of the dielectric substrate (glass) was plated with three thin conductive gold layers leaving two windows for the visualization of the cell culture.
Aufbau
A 35-mm Petri dish was held in the center of the exposure system by a 3-mm polystyrene mask.
Zusatzinfo
The structure propagated only the fundamental mode (quasi-transverse electromagnetic mode) in which the direction of the EF was almost parallel to the Petri dish surface and orthogonal to the glass microelectrode, thus minimising interference. The system assured a good homogeneity of the field applied to the sample.
