Schumann Resonances and Their Potential Applications: a Review Article

Abstract

Introduction. Schumann resonances is an important topic gains great interest in research areas which has extensive use of Schumann resonances in a variety of desplines such as biological evolutionary processes, the optimal functioning of the human brain waves and lightning-related studies. Materials and Methods. This dictates the major emphasis on economic, environmental, and engineering applications and hazard assessments in the form of earthquake and volcano monitoring. Results. This review is aimed at the reader generally unfamiliar with the Schumann Resonances. It is our hope that this review will increase the interest in SR among researchers previously unfamiliar with this phenomenon. Discussion and Conclusions. In this review paper, a brief introduction about Schumann resonances is presented. A general description of Earth’s ionosphere is outlined. The electromagnetic waves spectrum from lightning is discussed. The history of Schumann resonances is briefly presented. The connection of man with nature through Schumann resonances is introduced. Present Schumann resonances researches are briefly outlined. Schumann (global) electromagnetic resonances in the cavity Earth – ionosphere play a critical role in all biological evolutionary processes. However, there is a great need for independent research into the bio-compatibility between natural and manmade signals. Serious attention must now be paid to the possible biological role of standing waves in the atmosphere. Being a global phenomenon, Schumann resonances have numerous applications in lightning research.
