Classification of electromagnetic fields — In differential geometry and theoretical physics, the classification of electromagnetic fields is a pointwise classification of bivectors at each point of a Lorentzian manifold. It is used in the study of solutions of Maxwell s equations and has… … Wikipedia
Interface conditions for electromagnetic fields — Maxwell s equations describe the behavior of electromagnetic fields; electric field, electric displacement field, magnetic field and magnetic field strength. The differential forms of these equations require that there s always an open… … Wikipedia
Electromagnetic hypersensitivity — (EHS) sometimes also called electrosensitivity or electrical sensitivity (ES) is a condition in which people experience medical symptoms that they believe are caused by exposure to electromagnetic fields. Although effects of electromagnetic… … Wikipedia
Electromagnetic radiation and health — Electromagnetic radiation can be classified into ionizing radiation and non ionizing radiation, based on whether it is capable of ionizing atoms and breaking chemical bonds. Ultraviolet and higher frequencies, such as X rays or gamma rays are… … Wikipedia
Electromagnetic shielding — cages inside a disassembled mobile phone. Electromagnetic shielding is the process of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive and/or magnetic materials. Shielding is typically applied… … Wikipedia
Electromagnetic therapy — is a form of alternative medicine which claims to treat disease by applying electromagnetic energy to the body. [cite journal author=Gordon GA |title=Designed electromagnetic pulsed therapy: clinical applications |journal=J. Cell. Physiol.… … Wikipedia
Electromagnetic field solver — Electromagnetic field solvers (or sometimes just field solvers) are specialized programs that solve (a subset of) Maxwell s equations directly. They form a part of the field of electronic design automation, or EDA, and are commonly used in the… … Wikipedia
electromagnetic field — n a field (as around a working computer or a transmitting high voltage power line) that is made up of associated electric and magnetic components, that results from the motion of an electric charge, and that possesses a definite amount of… … Medical dictionary
Electromagnetic field — The electromagnetic field is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field.The electromagnetic field extends indefinitely throughout space and describes the… … Wikipedia
Electromagnetic wave equation — The electromagnetic wave equation is a second order partial differential equation that describes the propagation of electromagnetic waves through a medium or in a vacuum. The homogeneous form of the equation, written in terms of either the… … Wikipedia
