Abstract:
In an electroporosis treatment, an apparatus providing the required high electromagnetic field region at a desired location in a patient's body, said apparatus comprised of:a) an array of like-polarized antennas;b) an ultra-wideband (UWB) high-power microwave pulser outputting polarized pulses with rise times of 10 to 100 ps, pulse lengths of 10 ps to several nanoseconds, and of sufficient power to provide peak field strengths in the high field region of 10 to 100 kV/m; andc) a cable connecting said UWB pulser to each antenna in said array of antennas such that the length of each cable and the distance of each antenna from the desired location of the high field region causes the pulses to simultaneously arrive and add together in the desired location.
