Focusing Impulse Radiating Antennas allow the application of intense electric fields to biological tissue with centimeter spatial resolution. At low electric field strength, the scattered electromagnetic waves from the focal volume can be used to obtain information on the complex permittivity of the tissue at this location. Since the permittivity of tumor tissue varies considerably from that of healthy...
The application of nanosecond pulses to biological cells, which has been shown to lead to electroporation of not only the cell membrane, but also the membranes of subcellular structures, has spawned a new field of research: bioelectrics. A new domain of pulsed electric field interactions with cell structures and functions opens up when the pulse duration is reduced to values such that membrane charging...
