objective(s):electromagnetic radiations which have lethal effects on the living cells are currently also considered as a disinfective physical agent.   materials and methods: in this investigation, silver nanoparticles were applied to enhance the lethal action of low powers (100 and 180 w) of 2450 mhz electromagnetic radiation especially against escherichia coli atcc 8739. silver nanoparticles ...

This article presents a new method for generating low-frequency electromagnetic waves navigation and communication in challenging environments, such as underwater underground. The key concept is to disturb the magnetic energy stored around permanent magnet time-variant fashion. reluctance of medium modulated alter flux intensity direction (disturb energy) order achieve this goal. nonlinear prop...

Quantum dynamics of light waves traveling through a time-varying turbulent plasma is investigated via the SU(1,1) Lie algebraic approach. Plasma oscillations that accompany time-dependence of electromagnetic parameters of the plasma are considered. In particular, we assume that the conductivity of plasma involves a sinusoidally varying term in addition to a constant one. Regarding the time beha...

Recently, it has been shown that a new class of particle chains that support the simultaneous interplay of two-type rotations—geometric and electromagnetic—may possess strong nonreciprocity and one-way guiding effects. Here, we use the Z transform to develop a rigorous Green’s function theory for these one-way chains. A study of the chain’s spectra and its analytic properties in the complex spe...

We explore the feasibility of using a local spectral time-domain (LSTD) method to solve Maxwell's equations that arise in optical and electromagnetic applications. The discrete singular convolution (DSC) algorithm is implemented in the LSTD method for spatial derivatives. Fourier analysis of the dispersive error of the DSC algorithm indicates that its grid density requirement for accurate simul...

In this paper, the scattering of a plane monochromatic electromagnetic wave from a nanowire with circular cross-section in the transverse electric (TE) mode is simulated using the well-known Stratton-Chu surface integral equations. For an ordinary dielectric nanowire the refraction phenomenon is nicely simulated. In the case of a plasmonic nanowire no sign of surface plasmon excitation and prop...
