In article number 1700089 , Qiang Cheng, Tie Jun Cui, and co‐workers propose an acoustic magnifying lens based on transformation acoustics and effective medium theory, which is employed to realize far field sub‐wavelength resolution imaging over a broad bandwidth. The high‐resolution imaging effect is especially advantageous for the compact size and matched impedance at the interface, which are especially favorable in acoustic engineering.
