TY - JOUR AB - We describe a novel undergraduate research project that highlights the physics of metamaterials withacoustic waves and soda cans. We confirm the Helmholtz resonance nature of a single can bymeasuring its amplitude and phase response to a sound wave. Arranging multiple cans in arrayssmaller than the wavelength, we then design an antenna that redirects sound into a preferred direction.The antenna can be thought of as a new resonator, composed of artificially engineered meta-atoms,similar to a metamaterial. These experiments are illustrative, tactile, and open ended so as to enablestudents to explore the physics of matter/wave interaction AU - Wilkinson,JT AU - Whitehouse,CB AU - Oulton,RF AU - Gennaro,SD DO - 10.1119/1.4934596 EP - 20 PY - 2016/// SN - 0002-9505 SP - 14 TI - An undergraduate experiment demonstrating the physics of metamaterials with acoustic waves and soda cans T2 - American Journal of Physics UR - http://dx.doi.org/10.1119/1.4934596 VL - 84 ER -
