Abstract [en]

We present a metamaterial-based dual band microwave-absorber for radar applications, the structure of which consists of an array of closed ring resonators on a low profile substrate. Simulations show high absorption (absorptance > 90%) at dual frequencies i.e. 3 GHz and 9 GHz. The proposed absorber is insensitive to polarization (i.e., absorptance taking into account both co- and cross-polarization of reflected waves). Further, we show how the microwave absorber can be used to improve the performance of a radar system for short range applications, when positioned between the transmit and receive antennas. The error in estimated target distance is reduced and clutter reduction is improved.
