Converting ambient vibration energy into electrical energy by using piezoelectric energy harvester has attracted a lot of interest in the past few years. In this paper, a topology optimization based m...
A Frequency Decomposition Time Domain Model of Broadband Frequency-Dependent Absorption
frequency decomposition bandpass Gauss filter broadband ultrasound frequency-dependent attenuation time domain
2010/10/22
This study aims to extend the time-domain model for the frequency-dependent attenuation of a single frequency excitation to a broadband excitation via a finite frequency decomposition. Our model satis...
