DESIGN OF NARROW DISCRETE DISTANCES OF DUAL-/TRIPLE-BAND TERAHERTZ METAMATERIAL ABSORBERS

Abstract Various kinds of structure designs have been proposed to achieve the multiple-band metamaterial absorbers.However, the discrete distance of adjacent frequencies of multiple absorbers is considerably large, which will inevitably overlook a large amount of information hidden in Combination Oven Accessories the off-resonance absorption areas.
