Radar Absorbing Materials Based on Metamaterials
The use of metamaterial for design of radar absorbing material (RAM) is discussed. The typical features of the frequency dependencies of , , , of composites manufactured of different types of resonant inclusions are given as an example. The RAM characteristics obtained by the use of the composites are given. It is shown that it is possible to use for RAM design the metamaterials with both the positive values of , and negative ones. Making use of the frequency band with negative and it is possible to create a RAM with low reflection coefficient in a wide range of the angles of electromagnetic wave incidence.
