Characterization of a TEM cell-based setup for the exposure of biological cell suspensions to high-intensity nanosecond pulsed electric fields (nsPEFs)

In this paper, we propose and characterize a setup based on a Transverse ElectroMagnetic (TEM) cell to expose a Petri dish filled with a biological suspension to nanosecond high-voltage pulsed electric fields. Monopolar and bipolar pulses of 1.2 ns duration and 1.6 kV amplitude are delivered to the TEM cell. Time domain measurements and numerical results show that the system is well suited to deliver high-intensity pulsed electric fields with 1.2 ns duration and amplitudes of at least 100 kV/m.
