A large body of evidence now indicates that the amount of mercury released from dental amalgam fillings can be significantly accelerated by exposure to radiofrequency electromagnetic fields (RF-EMFs) such as common mobile phones and magnetic resonance imaging (MRI). Studies performed on the increased microleakage of dental amalgam restorations after exposure to RF-EMFs have further supported th...

A new electromagnetic energy harvester for harnessing energy from vibration induced by Kármán vortex street is proposed. It converts flow energy into electrical energy by fluid flow, vortex shedding from a bluff body and electromagnetic induction. An analytical design method for the energy harvester is developed. A prototype of the energy harvester is fabricated and tested. The prototype has a ...

The numerical calculations including voxel human model with an anatomical structure for electromagnetic field and temperature rise induced by electromagnetic energy absorption have been widely investigated over the past dozen years or so. This paper presents the computational electromagnetic dosimetry inside an anatomically based pregnant woman models exposed to electromagnetic wave during magn...

In quantum field theory, the splitting of the Hamiltonian into a strong and an electromagnetic part cannot be performed in a unique manner. In the present article, we propose a convention for disentangling these two effects: one matches the parameters of two theories – with and without electromagnetic interactions – at a given scale μ1, referred to as the matching scale. This method enables one...

Background information: Electromagnetic radiation is the transmission of energy in the form of waves having an electric and magnetic component. Almost all forms of electromagnetic radiation, which constitute the electromagnetic spectrum, such as radio waves, visible, infrared, and uliraviolet light, X-rays and gamma rays, are employed in the contemporary Hospital. There are some crucial decisio...

The significance of compressive thermal stresses generated during microwave heating on concrete surface delamination is investigated analytically in this paper. Microwave energy acts as an internal heating source that causes concrete to heat up. The amount of microwave energy dissipated in concrete depends on microwave frequency, microwave power and the electromagnetic properties of the concret...

A bi-isotropic magneto-electric metamaterials is modeled by two independent reservoirs. The reservoirs contain a continuum of three dimensional harmonic oscillators, which describe polarizability and magnetizability of the medium. The paper aimed to investigate the effect of electromagnetic field on bi-isotropic. Starting with a total Lagrangian and using Euler-Lagrange equation, researcher cou...

We address the inverse source problem of finding the time-harmonic current distribution (source) with minimum L2 norm (minimum energy) that generates a prescribed electromagnetic field outside the source’s region of support. Using the well-known multipole expansion of the electromagnetic field we compute (via a linear operator formalism) the sought-after minimum L2 norm-current distribution con...

It is known that classical electromagnetic radiation at a frequency in resonance with energy splittings of atoms in a dielectric medium can be described using the classical sine-Gordon theory. In this paper we quantize the electromagnetic field and compute quantum corrections to the classical results by using known results from the sine-Gordon quantum field theory.
