An electrical analogy to Mie scattering
Mie scattering is an optical phenomenon that appears when electromagnetic waves, in particular light, are elastically scattered at a spherical or cylindrical object. A transfer of this phenomenon onto electron states in ballistic graphene has been proposed theoretically, assuming a well-defined incident wave scattered by a perfectly cylindrical nanometer scaled potential, but experimental finge...
متن کاملCoherence effects in Mie scattering.
The scattering of a partially coherent beam by a deterministic, spherical scatterer is studied. In particular, the Mie scattering by a Gaussian Schell-model beam is analyzed. Expressions are derived for (a) the extinguished power, (b) the radiant intensity of the scattered field, and (c) the encircled energy in the far field. It is found that the radiant intensity and the encircled energy in th...
متن کاملAn Electrical Circuit and Computer System Analogy
This paper is concerned with the demonstration of an analogy between classical electrical circuits and computer systems with executing programs. The analogy is based on a Markov process framework for the mathematical formulation. The transition weights represent a set of measure one although they are not necessarily probabilities in the stochastic sense. Examples are included to show the analog...
متن کاملResonances in Mie scattering by an inhomogeneous atomic cloud
Despite the quantum nature of the process, collective scattering by dense cold samples of two-level atoms can be interpreted classically describing the sample as a macroscopic object with a complex refractive index. We demonstrate that resonances in Mie theory can be easily observable in the cooperative scattering by tuning the frequency of the incident laser field or the atomic number. The sol...
متن کاملMie scattering by an anisotropic object. Part I. Homogeneous sphere.
Establishing a vector spherical harmonic expansion of the electromagnetic field propagating inside an arbitrary anisotropic medium, we extend Mie theory to the diffraction by an anisotropic sphere, with or without losses. The particular case of a uniaxial material leads to a simpler analysis. This work opens the way to the construction of a differential theory of diffraction by a three-dimensio...
