Planar Multiband Metamaterial Absorber for Millimeter-wave Applications

<p>This research article deals with the metamaterial based absorbers. The proposed metamaterial absorber is composed with three layers, top and bottom metallic layers of copper and a middle dielectric spacer in between them. The present studt discusses the multiband features of the designed metamaterial absorber. The proposed absorber could be very useful for millimeter-wave applications.</p>
