The US Air Force has funded researchers at HRL Laboratories in Malibu, California to work on innovative new holographic techniques to create antennas that do not detract from an aircrafts aerodynamics.
The team are working on holographic impedance surfaces that will make antennas completely flush with the surface of the aircraft while still maintaining or even enhancing current protruding antenna capabilities.

The team are building the surfaces out of metallic materials on a substrate.
Programme manager at the Air Force Office of Scientific Research, Dr Arje Nachman said that the technology offers several benefits.
“One attractive benefit offered by these interesting surfaces is that if the tail of an aircraft obstructs the beam of an antenna then the tail can be covered by a suitably crafted impedance surface in such a way that the antenna beam flows around the tail as if the tail weren’t there,” Nachman said.
The HRL team is now trying to extend the capabilities of the electromagnetic impedance and experiment with practical implementations of it.
