Description
Summary:In this work, a flexible extremely low frequency mechanical antenna (ELFME) is fabricated by printing domain-editable magnets on macro-fiber-composite (MFC). When compared to existing magneto-electric composite antennas of similar volumes, our antenna exhibits an 18-fold increase in electromagnetic field emission intensity. Through an array design, we can further amplify the electromagnetic wave intensity. Moreover, this MFC driven, 3D printable design is ideal for making reconfigurable antenna that can be applied in complex-shaped mechanisms for geometrical reconfiguration and beam steering.
