Ultra-compact Very Low Frequency (VLF) Communication Systems for Underground, Underwater, and Hypersonic Flight
<Motivation and Innovation>
Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications,
Innovative cycles in the emergence of fundamentally new types of gyroscopes last for a period of forty to fifty years, and the change from one to another occurs only after a serious breakthrough in physics and technology. Gyros can measure the course of a scientific revolution.
