A two‐dimensional pyramidal shape metamaterial‐based absorber composed of multiple alternating metallic and dielectric thin films is proposed. This pyramid metamaterial absorber is a broadband, wide‐angle, omni‐directional and polarization‐insensitive light absorbing device. The absorption performance of the absorber is excellent, with an absorptivity of nearly 100% at the infrared waveband from 1 μm to 14 μm for normal incidence.
