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.

Electromagnetic theory is a triumph of classical physics. It was completed in a set of differential equations by Maxwell between 1855 and 1865. These are Maxwell’s equations for the electromagnetic field. In this chapter they are first given in the form derived from first principles in Electricity and Magnetism in this series and then reformulated for ...

Electromagnetic Fields and Bones
JAMA: The Journal of the American Medical Association, 1982The use of pulsing electromagnetic fields (PEMFs) and direct-current stimulation for the treatment of delayed and nonunion of fractures is proving to be a major advance in traumatic orthopedic surgery. In this issue ofThe Journal(p 623), Bassett and his co-workers summarize their experience in the use of PEMFs for nonunited fractures and failed ...

Quantization of the Electromagnetic Field [PDF]
, 2011 In this section we shall analyze the general solution \(A_\mu (x)\) to Maxwell’s equations in the vacuum by choosing as gauge fixing condition the so called Coulomb gauge differently from the Lorentz gauge condition used in the general discussion of the electromagnetic field given in Chap. 5.

In this chapter we recapitulate the classical and the quantum theories of the electromagnetic (em.) field. This is followed by a discussion of the concept of the field correlation functions and their role in characterizing the statistical and spectral properties of the field. We highlight some signatures of nonclassical features of the field carried by

To describe how the capacitance and inductance per unit length of a transmission line determine the speed of an electrical pulse. To obtain an expression for pulse speed and characteristic impendance in a transmission line. To show that pulse speed is independent of geometry and with no dielectric or magnetic materials present is the same as ...
