A tissue stimulation method which uses wave-guiding principles to construct a focused point of stimulation at any location within a region of electrically excitable living tissue. The excitation is formed through the constructive interference of different frequency wave energies, traveling at frequency-dependent velocities, which coalesce at the stimulation point. Further energy is brought to the stimulation point through reflection(s) at the boundaries of the wave-guiding structure. The resulting excitation signal depends upon several factors, including pulse envelope and duration, allowable frequency range, and stimulation time.
