WebMie's theory is valid for scattering of a plane electromagnetic wave by a homogeneous and isotropic sphere of arbitrary diameter. It encompasses both lossless and lossy spheres. Three continuous functions of frequency are presented. They contain information on the resonant frequencies, the Q-factors, and the output power losses of the sphere. WebThe specific absorption rate in a spherical head model from a dipole with metallic walls nearby Abstract: The head of the user of a mobile telephone is modeled by a lossy dielectric sphere excited by the near field of a dipole antenna and the effects of a metallic wall placed close to this system are analyzed.
Web1 de dez. de 2024 · The time-averaged spin toque components of a lossy dielectric sphere in a non-paraxial focused Gaussian beam were also computed (Chang and Lee, 1985), and angular accelerations about the propagation axis of absorptive dielectric droplets illuminated by circularly-polarized waves were numerically evaluated (Barton et al., 1989 ). Webseen in Fig.4b. Therefore, the polarization charge appears on the surface on the dielectric. In deriving Eq.(4.10) we can integrate over all the space. In this case the surface integral (the third term in this equation) vanishes due to the assumption of the finite volume of the dielectric. The expression for the potential then becomes [ ] 3 0 ...
