Abstract

We show that polarization-independent coherent perfect absorption can be realized in a simple dipole-like metasurface by precisely engineering the ratio between the scattering loss γs and the dissipation loss γl. This effect can be traced to a critical condition on the scattering matrix in a dipolar picture, which requires that the scattering and dissipation losses are equivalent, i.e., γs=γl, at the resonant frequency f0. This work expands the capability of metasurface in getting extreme optical properties, allowing for many potential applications.
