Abstract:

The control of chaos using tiny perturbations for the formation of time-limited waveformspulses and the synthesis of desired spectral characteristics is discussed. A technique for doing this using a symbolic dynamical system model is developed. This report is intended to demonstrate that the highly successful methods for controlling chaos with microscopic control signals might be used to form pulses and to control the power spectrum of a signal source such as a microwave power source or a laser. Since the control circuitry in a physical system would need to deliver only tiny low-power control perturbations, the realization of this technique in a high-power source would allow for the formation of shaped pulses with the source running in a highly efficient nonlinear chaotic mode. Shaping the power spectrum is of interest for the practical problem of delivering the energy to a band-limited transmission line or to an antenna.
