摘要： A passive, linear arrangement of a sonic crystal-based apparatus and method including a 1D sonic crystal, a nonlinear medium, and an acoustic low-pass filter, for permitting unidirectional broadband ultrasound propagation as a collimated beam for underwater, air or other fluid communication, are described. The signal to be transmitted is first used to modulate a high-frequency ultrasonic carrier wave which is directed into the sonic crystal side of the apparatus. The apparatus processes the modulated signal, whereby the original low-frequency signal exits the apparatus as a collimated beam on the side of the apparatus opposite the sonic crystal. The sonic crystal provides a bandpass acoustic filter through which the modulated high-frequency ultrasonic signal passes, and the nonlinear medium demodulates the modulated signal and recovers the low-frequency sound beam. The low-pass filter removes remaining high-frequency components, and contributes to the unidirectional property of the apparatus.

摘要： Phononic metamaterials and methods for reducing the group velocities and the thermal conductivity in at least partially crystalline base material are provided, such as for thermoelectric energy conversion. In one implementation, a method for reducing thermal conductivity through an at least partially crystalline base material is provided. In another implementation, a phononic metamaterial structure is provided. The phononic metamaterial structure in this implementation includes: an at least partially crystalline base material configured to allow a plurality of phonons to move to provide thermal conduction through the base material; and at least one disordered (e.g., amorphous) material coupled (e.g., as an inclusion, extending substructure, outer matrix, a coating to heavy inner inclusion, etc.) to the at least partially crystalline base material. The at least one disordered material is configured to generate at least one vibration mode by the oscillation of at least one atom within the disordered material to interact with the plurality of phonons moving within the base material and slow group velocities of at least a portion of the interacting phonons and reduce thermal conductivity through the base material.

摘要： Low frequency alarm tones emitted by life safety devices are more likely to notify sleeping children and the elderly. Disclosed herein is a life safety device equipped with a novel, compact, circumferential resonant cavity which increases the low frequency (400-600 Hz square wave) acoustic efficiency of an audio output apparatus formed by acoustically coupling an audio output transducer to the resonant cavity. The resonant cavity is a compact circumferential acoustic resonator with a captured mass of air within a ring shaped cavity significantly reducing the overall size of the resonator, thereby permitting the audio output apparatus to fit within the housing of conventional size life safety devices such as, but not limited to, residential and commercial smoke alarms and carbon monoxide alarms. The compact resonator is an acoustic compliant cavity with internal passages transforming axial traveling sound waves to circumferentially traveling sound waves thereby yielding a very compact geometry.
