We design a coherent perfect absorber (CPA) that can totally absorb the converging wave. Such a CPA is of subwavelength size and can be embedded in Maxwell's fish-eye lens and serve as a drain very well. Numerical simulations were performed to verify the functionalities.
PACS: 41.20.Jb – Electromagnetic wave propagation; radiowave propagation / 42.30.Va – Image forming and processing
