Pulsed power is applied to gases and liquids to produce plasmas, these may interact with living organisms. Plasma, known as the fourth state of matter, consists of charged and neutral particles and is characterized by a quasi-neutral state. Two types of plasma exist, nonthermal and thermal equilibrium. Nonthermal plasma, the type most frequently employed in the bioelectric field, has a gas temperature much lower than its electron temperature. The biocidal agents which may be produced by nonthermal plasmas are heat, electric fields, ultraviolet radiation, shock waves, and reactive chemical species. Additionally, secondary biological effects can be induced through post-discharge reactions of chemical species produced by plasma in gases and liquid. Interactions between pulsed electromagnetic fields and biological systems are studied in order to elucidate whether cellular systems are able to demodulate rapidly oscillating electric fields. Pulsed electromagnetic radiation comprises a central carrier frequency in the range from several GHz to about 1 THz and an electric field peak amplitude of tens of kV/m. High-power ultrawideband electromagnetic pulses (UWB-EMP) have recently been used for research in the bioelectric field to elucidate basic interactions with biological systems, to study induced biological effects, and to develop THz-based diagnostic technologies.
