Metamaterial based electromagnetic wave absorbers provide perfect absorption only over a narrow bandwidth. In this paper, broadband response is achieved through embedding of one resonator inside another in each unit cell of the metamaterial absorber lattice. These two resonators are oriented in the same direction to achieve reduced coupling between them realizing two absorption frequencies close to each other in order to broaden the efiective bandwidth. The paper presents such an absorber at 77GHz with a bandwidth of 8GHz and peak absorption of greater than 98%. The absorber is fabricated on 125"m thin and ∞exible polyimide substrate by patterning gold thin fllm in the shape of two split ring resonators as the metamaterial unit cell. The bandwidth is enhanced by more than a factor of two compared to what could be achieved from a metamaterial with single resonator structure.
