In the second edition of this popular textbook, apart from extending the presentation, application of electromagnetic theory for remote sensing, relativistic electrodynamics, meteor astronomy etc,. have been included. The work of pioneer investigators in respect of identity of light waves and electromagnetic waves so that the fundamental laws of optics can be derived from electromagnetic considerations, have been elaborated. Also, propagation through longer and longer distances have been extended.

Synopsis

Around 1864 Maxwell laid the foundation of electromagnetic theory, which formed the crowning achievement of 19th century physics. Max Born wondered how Maxwell could introduce the decisive step by adding the missing term "the displacement current" without proper empirical foundation. He argued that it "may be that Maxwell was first guided by mechanical models of the ether, later by reasons of mathematical perfection or beauty or however one may describe it as an act of genius". At the beginning of the 19th century, it was realized that the basic principles of Maxwell need not undergo any change barring the concept of all-prevailing ether. Otherwise, fundamental concepts of Maxwell remain the foundation of our present day concept of electromagnetism. As the range of Electromagnetic wave extended more and more to shorter wavelengths, it was realized that the extended regions have very significant applications for revealing the mysteries of nature. This work elaborates on the basic concepts of electromagnetic theory, and covers its extended regions discovered after World War II.
