Microwave metamaterials for increased survivability of future systems

Kurzfassung

Metamaterials are artificial materials with the effective electromagnetic parameters (e.g., refractive index, permittivity, permeability, surface impedance) that can be adjusted to almost any values, including those not encountered in nature. Metamaterials can serve therefore as an enabling technology for a great many of future applications in aerospace and navigation. The paper describes the results of the research work conducted at the Microwaves and Radar Institute of the German Aerospace Center in the several last years on the development of metamaterial devises that may help to control RCS of relevant targets, reduce interference and improve performance of antennas placed on various vehicles. The addressed topics include thin metamaterial absorbers, deflectors, meta-radomes and cylindrical cloaks.
