The contributions of different point source couples form hybrid focusing points. Ray-trace analyses are conducted for acoustic flat lenses with multi-source configurations. The finite-difference time-domain (FDTD) simulation of flat lenses with multi-source configurations demonstrates the establishment of pure and hybrid focusing points in a pyramidal constellation. The number of focusing points in the pyramidal constellation depends on the number of point sources. We propose an acoustic device for fine-tuning the location of a far-field hybrid focusing point and discuss its benefits for acoustic energy focusing application. © 2013 Chinese Physical Society and IOP Publishing Ltd.eninfo:eu-repo/semantics/closedAccessacoustic flat lensnegative refractionsonic crystal metamaterialswave focusingTheoretical demonstration of the hybrid focusing points of sonic crystal flat lenses and possible applicationsArticle22710.1088/1674-1056/22/7/0762012-s2.0-84880526635Q3
