Abstract: A system for transmitting a parametrically pumped sonic signal through a transmission medium to a remote location is disclosed. The preferred system, which is particularly intended for use as a sonic weapon, comprises a sound source; means for separating the sound into a plurality of discrete frequency components including a fundamental component and at least one additional component, each additional component having a frequency twice that of the next lowest frequency component; means for adjusting the phase difference between each frequency component and the next lowest frequency component to substantially 90.degree.; means for colinearly focusing the components on the remote location; and means for rendering the transmission medium nonlinear between the focusing means and the remote location.
Abstract: Method for destroying selected cells in a host without damage to non-selected cells comprises selecting a transmission path from an energy source (12) to the selected cells (30); determining one or more of the resonant frequencies of the selected cells (30); selecting as a destructive frequency one of the resonant frequencies at which the transmissibility of the selected cells (30) is higher than the transmissibility of the non-selected cells in the transmission path; and transmitting energy from the source (12) at the destructive frequency along the path with sufficient intensity to destroy the selected cells (30) without destroying the non-selected cells. Apparatus for practicing the method is also disclosed.
