摘要： We investigate theoretically and experimentally the absorption of a Helmholtz resonator (HR) array, an aluminum device operated in water. The HR array's period is 2 mm. The operating frequency range is similar to 0.2-0.7 MHz. We observed two transmission dips in both experimental and theoretical spectra. These dips are dominated by different resonance orders in the HR. The resonance behaviors are investigated with steady-fields simulation and can be represented by spring-mass models. This allows us to reduce the device's footprint significantly. 出版者： AIP Publishing 出版日期： 2012-07-30 出處： Applied Physics Letters, 2012-07, Vol.101 (5), p.51907 資源來源： AIP Journals (American Institute of Physics) 識別號： ISSN: 0003-6951 識別號： EISSN: 1077-3118 識別號： DOI: 10.1063/1.4742773
