Dual band metamaterial perfect absorbers with two absorption bands are highly desirable because of their potential application areas such as detectors, transceiver system, and spectroscopic imagers. We numerically and experimentally demonstrated polarization insensitive dual-band metamaterial perfect absorbers working in wide incident angles either based on two magnetic Mie resonances of a single dielectric “atom” with simple structure or on electric and magnetic Mie resonances of dielectric “molecules” consisted of four “atoms” of two different sizes. Two absorption bands with near unity absorptivity were achieved due to the simultaneous magnetic and electric resonances in the unit cell of metamaterial absorbers. Mie resonances of dielectric “atom” and “molecules” provide a simple way to design metamaterial perfect absorbers with high symmetry.
