N2 - Electromagnetic signals in the Ultra-Low Frequency (ULF) range 0.3-3 kHz are important for underground and underwater wireless communication systems, due to relatively low absorption through water, rock, and soil. However, the extremely large wavelength (~106 m) causes man-portable ULF antennas to be inefficient to the point of impracticality. In this work, we present a new ULF transmitter approach through direct production of oscillating magnetic fields by an array of magneto-mechanical torsional resonators. We demonstrate transmitter power optimization through eigenmode engineering, and discuss the formation of topologically protected states. Our work illuminates a path to MEMS-based ULF transmitters capable of communicating through water and earth over km distances.
