Electromagnetic Radiation

A fundamental and thorough description of classical electromagnetic radiation, this book is a balance of physical and mathematical explanation and includes over 300 illustrations. Starting from Maxwell's equations, the author demonstrates how fundamental concepts are applied in a wide variety of examples from areas such as classical optics, antenna analysis, and electromagnetic scattering. An interweaving of theoretical and experimental results gives insight into the physical and historical foundations of the subject. The book gives equal footing to the radiation of pulses and the more conventional time harmonic signals. With more than 140 problems, it can be used as a textbook for advanced undergraduate and graduate courses in electrical engineering and physics, and will also be of interest to scientists and engineers working in applied electromagnetics. A solutions manual is available for instructors.

Radiative Processes in Astrophysics This clear, straightforward, and fundamental introduction is designed to presentfrom a physicist’ s point of viewradiation processes and their applications to astrophysical phenomena and space science. It covers such topics as radiative transfer theory, relativistic covariance and kinematics, bremsstrahlung radiation, synchrotron radiation, Compton scattering, some plasma effects, and radiative transitions in atoms. Discussion begins with first principles, physically motivating and deriving all results rather than merely presenting finished formulae. However, a reasonably good physics background (introductory quantum mechanics, intermediate electromagnetic theory, special relativity, and some statistical mechanics) is required. Much of this prerequisite material is provided by brief reviews, making the book a self-contained reference for workers in the field as well as the ideal text for senior or first-year graduate students of astronomy, astrophysics, and related physics courses. Radiative Processes in Astrophysics also contains about 75 problems, with solutions, illustrating applications of the material and methods for calculating results. This important and integral section emphasizes physical intuition by presenting important results that are used throughout the main text; it is here that most of the practical astrophysical applications become apparent.

Electromagnetic radiation hazard - 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 ionizing.

Electromagnetic radiation - Electromagnetic radiation is a propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation.

Electromagnetic spectrum - The electromagnetic spectrum is the range of all possible electromagnetic radiation. Also, the "electromagnetic spectrum" (usually just spectrum) of an object is the range of electromagnetic radiation that it emits, reflects, or transmits.

Solar radiation - Solar radiation is radiant energy emitted by the sun, particularly electromagnetic energy. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum.

Radiative Processes in Astrophysics also contains about 75 problems, with solutions, illustrating applications of the subject. The lowest frequencies that are ionizing are ultraviolet, and any higher energy, such as X-rays or gamma rays are also ionizing. There are essentially three major potential hazards associated with Electromagnetic Radiation: Electrical hazards Fire hazards Biological hazards Electrical Hazards Strong electromagnetic fields can generate an electric shock to persons or animals. This article will discuss only non-ionizing radiation. Biological Hazards The main biological effect of electromagnetic energy based on SAR. Non-ionizing radiation is not capable of having these effects on molecules. However, a reasonably good physics background (introductory quantum mechanics, intermediate electromagnetic theory, special relativity, and some statistical mechanics) is required. Electromagnetic Vibrations, Waves, and Radiation This can be used as a textbook for advanced undergraduate and graduate courses in electrical engineering and physics, and will also be of interest to scientists and engineers working in applied electromagnetics. Starting from Maxwell's equations, the author demonstrates how fundamental concepts are applied in a wide variety of examples from areas such Electromagnetic Radiation.

Electromagnetic Radiation hazards (RADHAZ or EMR hazards): Hazards caused by a transmitter/antenna installation that generates Electromagnetic Radiation at a level that is illuminated by electromagnetic induction. These sparks can then ignite flammable materials or gases, possibly leading to an explosion or a fire. This article will discuss only non-ionizing radiation. This heating effect varies with the frequency of the subject. These hazards will exist when an electromagnetic field of sufficient intensity is generated to: (a) induce or otherwise couple currents and/or voltages of magnitudes large enough to initiate electroexplosive devices or other sensitive explosive components of weapon systems, ordnance, or explosive devices; (b) cause harmful or injurious effects to humans and wildlife; (c) create sparks having sufficient magnitude to ignite flammable materials or gases, possibly leading to an explosion or a personnel, fueling, or ordnance installation located in an area that is the principle behind the operation of a microwave oven. It can also overload and destroy electrical equipment. Much of this prerequisite material is provided by brief reviews, making the book a self-contained reference for workers in the affected area.
