A MEchanically Based Antenna (AMEBA)
Abstract
The A MEchanically Based Antenna (AMEBA) program developed and demonstrated efficient radio frequency (RF) transmitters operating in the Ultra-Low Frequency (ULF) and Very Low Frequency (VLF) ranges for portable applications in underground and underwater communications. Whereas traditional antennas generate electromagnetic waves by driving current through a conductive material, AMEBA took the novel approach of mechanically moving an electrical charge or magnet to generate electromagnetic waves at ULF and VLF. AMEBA focused on developing both the materials and precision-controlled electromechanical systems required for an efficient transmitter system. This new capability enables a range of applications including wireless communications for use over very long distances and short-range underground and underwater RF links. Other potential applications include terrestrial navigation systems for GPS-denied environments and ground-penetrating radar for detecting unexploded ordnance, underground facilities, and tunnels.
