Electromagnetism

This research develops a subject evaluation report on electromagnetics. The approach to this subject evaluation is to use concepts and principles presented by John D. Kraus in Electromagnetics to analyze and describe contemporary professional work in this field. Major work with electromagnetic theory in the contemporary period involves the application of electromagnetic wave-scattering, antenna, and distribution concepts. Both acoustics and imagery are involved in this work. This contemporary work is addressed in this subject evaluation within the context of communications applications. Electromagnetic radio wave concepts and technology are prominent in this work. Additionally, a brief historical background is presented, as is a statement of contemporary public interest in electromagnetism. Contemporary public interest ranges from planetary concepts of electric transmission lines.

Historical Background and Contemporary Public Interest in Electromagnetism

The traditional conception of the physical world was that it consisted of four elements, which were earth, air, fire and water. Similarly, modern physics also characterizes the physical world within the context of four forces, which are gravity, electromagnetism, and both strong and the weak nuclear forces. Contemporary physics holds that the elements are not primary, but are themselves composed from particles, such as protons and electrons, and that, in turn, these particles are composed of simple entities named quarks.

Except for the change in nomenclature, this modern concept is very nearly the same as that conceptualized by the ancient Greek Heraclitus 2,500 years ago when he is said to have proclaimed that: "It ever was, and is, and shall be, ever-living fire, in measures being kindled and in measures going out." Other ancient Greek thinkers held alternative views: Thales said that: "All is water, and the world is full of gods." Anaximenes thought that ...
