Abstract

In addressing the challenging problems of underwater communication, mechanical antenna (MA) provides a new direction for greatly reducing the size of low frequency communication equipment and breaking through the Chu-Harrington limit [1,2]. MA refers to the generation of low-frequency electromagnetic waves by mechanically driving materials with strong electric or magnetic fields. This direction has attracted many researchers from fields such as materials, mechanics, and mechanics to conduct research. Various forms of MA currently exist, but research on their modulation methods remains limited. The modulation methods of MA primarily include amplitude modulation, frequency modulation, and phase modulation [3]. Frequency modulation is widely used due to its excellent anti-interference properties. This study proposed and experimentally proved a method of encoding using the transient information of modal transformation based on the sphere-string mechanical antenna. The modulation method greatly improves the transmission speed of information and provides more ideas for the modulation method of MA.
