Metamaterials are specifically engineered to produce electromagnetic properties that not available in natural materials. Multiband metamaterial (MM) absorbers achieve great research interest due their applications sensing, filtering, and stealth. These mostly made of multilayered complex geometrical structures. In this work, a single-layered cartwheel-shaped (CWS), polarization-insensitive MM a...

This paper presents an simulation study using CST microwave studio. In this work very simple design are used based on metamaterial to construct perfect absorber. It is a semi-square copper loop placed top of dielectric layer separate from ground plate. structure provides two absorption region with peaks in average 99.98%. due dipole resonance the main and secondary diameter ring. addition, dime...

We present a broadband microwave metamaterial (MM) absorber, the unit cell of which consists of a lumped-resistor-loaded electric-inductive-capacitive (ELC) resonator and a cut-wire on the same side of a flexible polyimide substrate. In contrast to the common MM absorber, the metallic pattern layer of the proposed structure is placed parallel to the direction of propagation of the incident wave...
