Nonthermal electromagnetic fields: From first messenger to therapeutic applications
Electromagnetic Biology and Medicine, 2013Nonthermal pulsed electromagnetic fields, from low frequency to pulse-modulated radio frequency, have been successfully employed as adjunctive therapy for the treatment of delayed and non-union fractures, fresh fractures and chronic wounds.

General Electromagnetic Fields [PDF]
, 1995 In this Chapter we will derive expressions for general field and alignment errors to be used in the Hamiltonian perturbation theory. Pure electromagnetic multipole fields have been derived in [2.1] from the Laplace equation while ignoring kinematic terms as well as higher-order field perturbations.

On the sampling of electromagnetic fields
2010 URSI International Symposium on Electromagnetic Theory, 2010We address the problem of extracting the maximum amount of information on an electromagnetic field over a domain D O from field samples on a domain D I , with a priori information on the radiating source. The problem is faced in two steps. In the first one, the source reconstruction is dealt with by taking into account the available a priori ...

Atoms in Electromagnetic Fields
1994Atoms in weak broadband quasi-resonant fields - light shifts atoms in linear superpositions of Zeeman sublevels-Zeeman coherences atoms in strong radiofrequency fields - the dressed-atom approach in the RF domain atoms in intense resonant laser beams - the dressed-atom approach in the optical domain the radiative cascade of the dressed atom - photon ...

We concluded the previous chapter with the hope that the field may provide the way out of the paradoxes of thermodynamics. We point out that various intuitive ideas underlying field theory, such as action by ‘contact’, the idea of ‘locality’ or a ‘chain of causes’, or the mechanical model provided by the field, are respectively unintelligible, illusory,

The combined action functional for the electromagnetic and gravitational fields in the presence of charged matter is given by $$ S\equiv S_{\rm G}[g_{\mu\nu}]+ S_{\rm E}[g_{\mu\nu},A_\mu] + S_{\rm M}[g_{\mu\nu},A_\mu,\Phi^A], $$ where S M is the action functional for the material system and the ? A are the matter dynamical variables.

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.
