The remedial electromagnetic field
Journal of Biomedical Engineering, 1989This paper reviews the history and development of electric and electromagnetic fields used in the treatment of a variety of medical conditions. An account is given of their clinical use and some suggestions are advanced for an explanation of a possible physiological mechanism.

Fundamentals of Physics II, 2018
This chapter examines solutions to the Maxwell equations in a vacuum: monochromatic plane waves and their polarizations, plane waves, and the motion of a charge in the field of a wave (which is the principle upon which particle detection is based).

Electromagnetic Fields and Electromagnetic Waves
2017Microwaves are not a simple heat source. Substances are heated directly by electromagnetic waves at energies commensurate with microwaves. Therefore, an understanding of the nature of these electromagnetic waves is the dominating discussion on microwave heating.

Basic characteristics of electromagnetic fields in the microwave, radiofrequency, and extremely low frequency ranges and their interactions with biological tissues are introduced, and parameters such as polarization and specific absorption rate used for safety assessment are highlighted. Techniques and instrumentation for measuring these parameters are

Abstract This chapter presents the basic notions of electromagnetism, chiefly the balance laws in global and local form. The corresponding Maxwell’s differential equations and boundary conditions are then derived. Electromagnetic potentials are introduced along with gauge conditions. They are then applied to determine the electromagnetic

ELECTROMAGNETIC FIELD AND ELECTROMAGNETIC WAVES
РАДИАЦИОННАТА БЕЗОПАСНОСТ В СЪВРЕМЕННИЯ СВЯТEMF causes different effects depending on whether it acts on a conductor or a dielectric. In wires, EMF causes the appearance of alternating currents - i.e. sets electrons and ions in motion around their centers of equilibrium with a frequency determined by the EMF frequency. In dielectrics, EMF causes orientational polarization, i.e.
