Abstract: Wide-angle polarization-insensitive triple-band perfect metamaterial absorbers (PMAs) based on single resonators are investigated. Generally speaking, the single resonator can only generate an absorption peak induced by the excitation of a fundamental resonance. Here, the designed… read more here.
