Time reversal focusing of high amplitude sound in a reverberation chamber.
Time reversal (TR) is a signal processing technique that can be used for intentional sound focusing. While it has been studied in room acoustics, the application of TR to produce a high amplitude focus of sound in a room has not yet been explored. The purpose of this study is to create a virtual source of spherical waves with TR that are of sufficient intensity to study nonlinear acoustic propa...
متن کاملTime reversed reverberation focusing in a waveguide.
Time reversal mirrors have been applied to focus energy at probe source locations and point scatterers in inhomogeneous media. In this paper, we investigate the application of a time reversal mirror to rough interface reverberation processing in a waveguide. The method is based on the decomposition of the time reversal operator which is computed from the transfer matrix measured on a source-rec...
متن کاملEfficient Determination of Reverberation Chamber Time Constant
Determination of the rate of energy loss in a reverberation chamber is fundamental to many different measurements such as absorption cross-section, antenna efficiency, radiated power, and shielding effectiveness. Determination of the energy decay time-constant in the time-domain by linear fitting the power delay profile, rather than using the frequencydomain quality-factor, has the advantage of...
متن کاملA time-reversal mirror with variable range focusing
Recently a time-reversal mirror ~or phase-conjugate array! was demonstrated experimentally in the ocean that spatially and temporally refocused an incident acoustic field back to the original position of the probe source @Kuperman et al., J. Acoust. Soc. Am. 103, 25–40 ~1998!#. Here this waveguide time-reversal mirror technique is extended to refocus at ranges other than that of the probe sourc...
متن کاملRobust time reversal focusing in the ocean.
Recent time-reversal experiments with high-frequency transmissions (3.5 kHz) show that stable focusing is severely limited by the time-dependent ocean environments. The vertical focal structure displays dynamic variations associated with focal splitting and remerging resulting in large changes in focal intensity. Numerical simulations verify that the intensity variation is linked to the focal s...
