Ultrathin millimeter-wave–absorbing film for automotive radars based on an epsilon iron oxide/carbon nanotube composite material
An ultrathin 213-μm film was prepared composed of ε-Ga 0.45 Fe 1.55 O 3 nanomagnets and carbon nanotubes. The film absorbs 99.3% of 79 GHz millimeter waves, enabling efficient suppression of unwanted radar signals in automotive systems.
