This book deals with the SLF/ELF wave propagation, an important branch of electromagnetic theory. The SLF/ELF wave propagation theory is well applied in earthquake electromagnetic radiation, submarine communication, thunderstorm detection, and geophysical prospecting and diagnostics. The propagation of SLF/ELF electromagnetic waves is introduced in various media like the earth-ionospheric waveguide, ionospheric plasma, sea water, earth, and the boundary between two different media or the stratified media. Applications in the earthquake electromagnetic radiation and the submarine communications are also addressed. This book is intended for scientists and engineers in the fields of radio propagation and EM theory and applications.

Prof. Pan is a professor at China Research Institute of Radiowave Propagation in Qingdao (China).

Dr. Li is a professor at Zhejiang University in Hangzhou (China).

Prof. Wei-Yan Pan
Prof. Pan is a professor at China Research Institute of Radiowave Propagation. He was once a visiting scholar at Harvard University from 1983 to 1985 and from June to December in 1993, where he was guided by Prof. Tai Tsun Wu. In the past 50 years, Prof. Pan has published over 100 papers (over 20 are international ones) in radio propagations of ELF/SLF/VLF/LF electromagnetic waves. The selected papers include: Pan WY, IEEE Trans. EMC, 27, pp. 88-95, 1985; Pan WY, J. Appl. Phys., 58, 3963-3974, 1985; Pan WY., IEEE Trans. AP, 34, pp. 267-277, 1986; ;Pan WY, Shen HM, Radio Sci., 29, 1231-1236, 1994; Zhang HQ, Pan WY, Radio Sci., 37, 1060, doi: 1029/2000RS002348; Pan WY and Zhang HQ, Radio Sci., 38, 1059, doi: 10.1029/2002RS002639).

In 2004, Prof. Pan published a monograph on LF/VLF propagation (Pan WY, LF VLF ELF Wave Propagation (In Chinese), Chengdu, China: UESTC Press, 2004). This book introduces the theory and applications of LF/VLF wave propagations in detail, and the progress for ELF/SLF regions before 2000. In the following ten years, Professor Pan, together with his team at China Research Institute of Radiowave Propagation, made a further great progress on the SLF/ELF wave propagation and its applications theoretically and experimentally.

Prof. Kai Li
During the past decades, Prof. Kai Li has published 34 international journal papers on the studies of ELF/SLF/VLF/LF electromagnetic waves propagation. In the past three years, he and his research group at Zhejiang University has achieved a great progress on the SLF/ELF wave propagation and applications theoretically. Their paper entitled Propagation of ELF Electromagnetic Waves in the Lower Ionosphere (accepted by IEEE Transactions on Antennas and Propagation), addressed a novel analytical solution for the ELF wave propagation in the inhomogeneous lower ionosphere for the first time. Prof. Li has also published a book with Springer in 2009 (Kai Li, Electromagnetic fields in stratified media, ZJU Press, China and Springer-Verlag, Germany, March, 2009).
