摘要:

聲學(xué)超構(gòu)材料是當(dāng)前聲學(xué)和材料學(xué)一個(gè)熱門(mén)的研究領(lǐng)域。聲學(xué)超構(gòu)材料可定義為：通過(guò)對(duì)材料在特征物理尺度上進(jìn)行人工設(shè)計(jì)制備，使其具有超越常規(guī)材料的聲學(xué)性能的一種人工序構(gòu)的復(fù)合材料。其亞波長(zhǎng)特性、超常聲學(xué)性能以及顛覆性應(yīng)用的可能吸引了學(xué)界和工程界的關(guān)注。21世紀(jì)以來(lái)，隨著增材制造技術(shù)的發(fā)展，聲學(xué)超構(gòu)材料的實(shí)驗(yàn)室加工與制備問(wèn)題得以解決，然而，聲學(xué)超構(gòu)材料的工程應(yīng)用仍然面臨著批量制造困難、使用場(chǎng)景不明、生產(chǎn)成本高昂等方面的嚴(yán)峻挑戰(zhàn)。介紹了各類(lèi)常見(jiàn)的聲學(xué)超構(gòu)材料及其研究現(xiàn)狀，討論各類(lèi)聲學(xué)超構(gòu)材料實(shí)用化面臨的困難和挑戰(zhàn)，簡(jiǎn)述聲學(xué)超構(gòu)材料研究和實(shí)驗(yàn)的最新方法，最后展望了未來(lái)聲學(xué)超構(gòu)材料實(shí)用化研究的方向。

Abstract:

Acoustic metamaterials are one of the current research hotspots in acoustics and materials science. Acoustic metamaterials are generally defined as a kind of composite materials, which are designed by artificial structures on characteristic physical scales and exhibit acoustic properties that exceed conventional materials. Due to the excellent subwavelength acoustic performance and the possible applications in some extreme condition, the acoustic metamaterials have attracted much attention. In recent years, a large number of laboratory-grade acoustic metamaterials have been reported with the continuous maturity of additive manufacturing technology. However, due to high production costs and complex preparation processes, the application of acoustic metamaterials is still facing severe challenges. In this paper, the current research status of several kinds of acoustic metamaterials is introduced in detail, the technical and technological problems in applications for them are discussed in detail, and the latest research progress of testing and research methods for acoustic metamaterials is briefly introduced. Finally, the future prospect and development directions of acoustic metamaterials was forecasted from the perspective of practicality.
