Abstract :
A bandwidth-enhanced microwave absorber using a double resonant metamaterial is presented. Its bandwidth is increased compared with previous metamaterial absorbers. The proposed absorber has a thin configuration and its performance is constant for different polarisations. Numerical and experimental results support the proposed absorber´s performance.
