Studies and Simulation Analysis of Underground Ultra-Low Frequency Electromagnetic Communication

Transmitting electromagnetic signals through the conductive medium underground, the more successful method is through the earth to transmit electromagnetic signals. To enable the signals not be severely attenuated, usually the ultra-low frequency electromagnetic communication is more suitable for the downhole communication, which has an important research value and significance. In this paper, the underground ultra-low frequency electromagnetic communication studies and simulation analysis is expatiated by introducing ultra-low frequency electromagnetic communication circuit design method, experimental design and analysis, signal processing, as well as different communication principles´ compare. The receiving device designed can receive the signals from the transmitting device and this device can achieve communication tasks.
