Electromagnetic wave absorbed

The purpose of this article is to investigate the dielectric response of fullerenes under static uniform electric fields in order to predict their effects in composite materials used for coating of electronic circuits. This study is a part of the larger project devoted to electromagnetic wave absorbing media. [Pg.266]

Polymer-based nanocomposites reinforced with nanoparticles (NPs) have attracted much interest due to their homogeneity, relatively easy processability, and tunable physicochemical properties, such as mechanical, magnetic, electric, thermoelectric, and electronic properties [2,19-36], High particle loading is required for certain industrial applications, such as electromagnetic-wave absorbers [37,38], photovoltaic cells (solar cells) [39,40], photo detectors, and smart structures [41 3]. A nanoparticle core with a polymer shell renders many industrial applications possible, such as nanofluids and magnetic resonance imaging (MRI). [Pg.504]

This model was later expanded upon by Lifshitz [33], who cast the problem of dispersive forces in terms of the generation of an electromagnetic wave by an instantaneous dipole in one material being absorbed by a neighboring material. In effect, Lifshitz gave the theory of van der Waals interactions an atomic basis. A detailed description of the Lifshitz model is given by Krupp [34]. [Pg.147]

Radiation. All materials radiate thermal energy in the form of electromagnetic waves. When this radiation falls on a second body it may be partially reflected, transmitted, or absorbed. It is only the fraction that is absorbed that appears as heat in the body. [Pg.381]

There are two principle ways for optical detection of protein concentrations either the macromolecule or its label emits energy (after excitation by light) -then a fluorescence signal can be measured or it absorbs energy from electromagnetic waves passing the sample - then the optical absorption of the sample can be measured by UV/Vis spectroscopy and concentrations can be calculated according to Lambert-Beers Law. [Pg.79]

Let us consider thermal radiation in a certain cavity at a temperature T. By the term thermal radiation we mean that the radiation field is in thermal equilibrium with its surroundings, the power absorbed by the cavity walls, Fa (v), being equal to the emitted power, Pe v), for all the frequencies v. Under this condition, the superposition of the different electromagnetic waves in the cavity results in standing waves, as required by the stationary radiation field configuration. These standing waves are called cavity modes. [Pg.39]

When a beam of x-rays strikes an electron, some of the energy is momentarily absorbed, displacing the electron from its unperturbed position. This sets the electron in periodic motion with the same frequency as that of the exciting radiation. As a result the electron radiates an electromagnetic wave in all directions with the same frequency as the exciting radiation. This leads to the experimental observation that the incident radiation is scattered by the electron. A theoretical analysis (10, 11) of these events leads to the Thompson scattering equation which relates the intensity of x-rays scattered by a single electron, Ie, to that of the incident non-polarized x-radiation, I0 ... [Pg.334]
