摘要
The Doppler shift is investigated in a one-dimensional system with a moving source. Theoretical findings are confirmed by numerical simulations of optical and acoustical wave propagation in a simple metamaterial model, showing the reversed shift and the existence of multiple frequency modes. The properties of these waves are discussed, and the effect of absorption on the phenomenon is outlined. (C) 2015 Optical Society of America
