Abstract Scope |
In order to break through the limitations of traditional low-frequency antenna, such as high cost communication equipment,large system structure and high power consumption. A kind of magnetoelectric composite material is designed by combining piezoelectric fiber composite material with magnetostrictive material, which realizes the energy conversion between electric-elastic and magnetic through stress transfer, and realizes the low-frequency electromagnetic wave emission and short-range low-frequency communication. We regulate its low-frequency electromagnetic radiation performance through the overall material design, verify the direct coupling relationship between the mechanical frequency of material tip displacement and the frequency of electric field change, and test its magnetic induction intensity to prove that it can achieve communication at low frequencies. |
