Abstract
Phononic crystal has attracted increasing interests because of their fascinating properties in manipulating classical waves. To improve the practicability of the phononic crystal with enforcing adjustability for adapting to various application scenarios, a tunable phononic crystal based on magnetofluid was fabricated and characterised in this work. The manipulation capacity of the proposed phononic crystal to acoustic waves was analysed theoretically and experimentally. Results demonstrate that the magnetofluid phononic crystal possesses controllable bandgaps and can isolate or manipulate the transmission of the acoustic waves. The potential applications are discussed and prospected.
