Acoustically Actuated Ultra-Compact NEMS Magnetoelectric Antennas

State-of-the-art compact antennas rely on electromagnetic wave resonance, which leads to antenna sizes that are comparable to the electromagnetic wavelength. As a result, antennas typically have a size greater than one-tenth of the wavelength, and further miniaturization of antennas has been an open challenge for decades. Here we report on acoustically actuated nanomechanical magnetoelectric (ME)

Small Antennas Could be a Big Deal for the Air Force

Researchers at the Air Force Research Laboratory’s Materials and Manufacturing Directorate, in partnership with Northeastern University, recently developed an ultra-compact antenna that uses a whole different approach in transmitting and receiving signals. This breakthrough could be a big step in the miniaturization of many military and commercial communication systems. Typical antennas rely on size to
