ECE PhD Defense: "Acoustically Actuated Ultra-compact NEMS Magnetoelectric Antennas," Hwaider Lin

Abstract: Antenna miniaturization is one of the fundamental challenges for decades. Conventional small antennas use electric currents for radiation which relies on electromagnetic wave resonance that leads to antenna sizes comparable to the electromagnetic wavelength l0. Here we demonstrated a new antenna mechanism: Acoustically actuated nanomechanical magnetoelectric (ME) antennas with released ferromagnetic/piezoelectric thin film resonators, which can generate magnetic currents for radiation and miniaturize the antenna size magnitude of 1 to 2 orders smaller with one of the highest gains...
